Answer 2

Matching Organic Compounds with Their Formulas

1. C6H5OH - This formula corresponds to the compound phenol. - Phenols are a class of organic compounds that contain a hydroxyl group (OH) attached to an aromatic hydrocarbon group. - Source: 2. CH3-CH2-COO-CH3 - This formula corresponds to the compound simple esters. - Simple esters are organic compounds formed by the reaction between carboxylic acids and alcohols, resulting in the formation of an ester functional group. - Source: 3. CH3-CH2-CH2-CH2-OH - This formula corresponds to the compound alcohols. - Alcohols are organic compounds that contain a hydroxyl group (-OH) bonded to a carbon atom. - Source: 4. CH3-CH2-CH(CH3)-CHO - This formula corresponds to the compound aldehydes. - Aldehydes are organic compounds containing a formyl group (−CHO), which is a carbon atom double-bonded to an oxygen atom and single-bonded to a hydrogen atom. - Source:

Summary

The given formulas correspond to the following classes (groups) of organic compounds: 1. C6H5OH: Phenols 2. CH3-CH2-COO-CH3: Simple Esters 3. CH3-CH2-CH2-CH2-OH: Alcohols 4. CH3-CH2-CH(CH3)-CHO: Aldehydes
