please solve the complete question please. Thank you ?? References) Choose condensed structural formulas for the two carboxylic acids with the molecular formula C4Hg02 Select all that apply) CH3CH2CH2COH CH3CHCOH CHa CH3CH2COCH3 CH3COCH2CH3 Solution Ans 1 : The first two compounds are the correct choices : CH3CH2CH2C=O(OH) and CH3CH(CH3)C=O(OH) These compounds are the carboxylic acids with the characteristic carboxylic acid group (-COOH) in them . The other two compounds are esters , as they have (-COO-) group in them , which does not qualify as ester. .
