The Following Compound Has The Condensed Formula: CH.COOH. Which Functional Group Does This Compound Have?A. Alcohol B. Ketone C. Aldehyde D. Organic Acid
The Condensed Formula: A Key to Identifying Functional Groups
In organic chemistry, the condensed formula is a shorthand way of representing the molecular structure of a compound. It consists of a series of letters and numbers that indicate the types and numbers of atoms present in the molecule. The condensed formula CH.COOH is a classic example of how this notation is used to represent a compound.
Understanding the Condensed Formula
To identify the functional group present in the compound with the condensed formula CH.COOH, we need to break down the formula and understand its components. The formula consists of three parts: CH, COOH, and the dot (.) separating the first two parts. The CH part represents a methyl group (CH3), which is a hydrocarbon group consisting of one carbon atom bonded to three hydrogen atoms. The COOH part represents a carboxyl group, which is a functional group consisting of a carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group (OH).
Identifying the Functional Group
Now that we have broken down the condensed formula, we can identify the functional group present in the compound. The presence of the COOH group is a clear indication that the compound is an organic acid. Organic acids are a class of compounds that contain a carboxyl group (-COOH) as their functional group. This group is characterized by its acidic properties, which allow it to donate a proton (H+ ion) in aqueous solutions.
Key Characteristics of Organic Acids
Organic acids have several key characteristics that distinguish them from other functional groups. Some of the most important characteristics include:
- Acidic properties: Organic acids are characterized by their ability to donate a proton (H+ ion) in aqueous solutions.
- Carboxyl group: The presence of a carboxyl group (-COOH) is a clear indication that a compound is an organic acid.
- pH-dependent behavior: Organic acids exhibit pH-dependent behavior, with their acidic properties becoming more pronounced in acidic solutions.
Comparison with Other Functional Groups
To further reinforce our identification of the functional group present in the compound with the condensed formula CH.COOH, let's compare it with other functional groups.
- Alcohol (A): Alcohols are characterized by the presence of a hydroxyl group (-OH) bonded to a carbon atom. The condensed formula CH.COOH does not contain a hydroxyl group, so it is not an alcohol.
- Ketone (B): Ketones are characterized by the presence of a carbonyl group (C=O) bonded to two carbon atoms. The condensed formula CH.COOH does not contain a carbonyl group, so it is not a ketone.
- Aldehyde (C): Aldehydes are characterized by the presence of a carbonyl group (C=O) bonded to a hydrogen atom. The condensed formula CH.COOH does not contain a carbonyl group bonded to a hydrogen atom, so it is not an aldehyde.
Conclusion
In conclusion, the compound with the condensed formula CH.COOH is an organic acid. The presence of a carboxyl group (-COOH) is a clear indication of its acidic properties and functional group identity. By understanding the condensed formula and identifying the key characteristics of organic acids, we can confidently conclude that the compound in question is an organic acid.
Key Takeaways
- The condensed formula CH.COOH represents a compound with a carboxyl group (-COOH) as its functional group.
- Organic acids are characterized by their acidic properties, carboxyl group, and pH-dependent behavior.
- The compound with the condensed formula CH.COOH is not an alcohol, ketone, or aldehyde.

Q&A: Organic Acids and Functional Groups
In our previous article, we discussed the condensed formula CH.COOH and identified it as an organic acid. In this article, we will answer some frequently asked questions about organic acids and functional groups.
Q: What is the difference between an organic acid and a carboxylic acid?
A: The terms "organic acid" and "carboxylic acid" are often used interchangeably, but technically, a carboxylic acid is a specific type of organic acid that contains a carboxyl group (-COOH). All carboxylic acids are organic acids, but not all organic acids are carboxylic acids.
Q: What is the pH-dependent behavior of organic acids?
A: Organic acids exhibit pH-dependent behavior, meaning that their acidic properties become more pronounced in acidic solutions. This is because the carboxyl group (-COOH) can donate a proton (H+ ion) in aqueous solutions, making the solution more acidic.
Q: How do organic acids differ from inorganic acids?
A: Organic acids differ from inorganic acids in their structure and properties. Inorganic acids, such as hydrochloric acid (HCl) and sulfuric acid (H2SO4), are typically strong acids that completely dissociate in aqueous solutions. Organic acids, on the other hand, are typically weak acids that only partially dissociate in aqueous solutions.
Q: What are some common examples of organic acids?
A: Some common examples of organic acids include:
- Acetic acid (CH3COOH): Found in vinegar and used as a food preservative.
- Citric acid (C6H8O7): Found in citrus fruits and used as a food additive.
- Malic acid (C4H6O5): Found in fruits and used as a food additive.
- Tartaric acid (C4H6O6): Found in grapes and used as a food additive.
Q: What are some common uses of organic acids?
A: Organic acids have a wide range of applications, including:
- Food and beverage industry: Used as food preservatives, flavor enhancers, and acidity regulators.
- Pharmaceutical industry: Used as active ingredients in medications and as excipients in drug formulations.
- Cosmetic industry: Used as skin care ingredients and as pH adjusters in personal care products.
- Industrial applications: Used as cleaning agents, rust inhibitors, and as components in the production of plastics and other materials.
Q: How do I identify an organic acid in a molecule?
A: To identify an organic acid in a molecule, look for the presence of a carboxyl group (-COOH). This group is typically characterized by its acidic properties and its ability to donate a proton (H+ ion) in aqueous solutions.
Q: What are some common functional groups that are related to organic acids?
A: Some common functional groups that are related to organic acids include:
- Carbonyl group (C=O): Found in ketones and aldehydes.
- Hydroxyl group (-OH): Found in alcohols.
- Ester group (COO-): Found in esters.
Conclusion
In conclusion, organic acids are an important class of compounds that have a wide range of applications in various industries. By understanding the properties and characteristics of organic acids, we can better appreciate their importance and potential uses.
