Question

esters have the general formula rcoor, where r may be a hydrogen atom, an alkyl group, or an aryl group, and r may be an alkyl group or an aryl group or a hydrogen atom. true false

Explanation:

Esters are formed from the reaction of a carboxylic acid (with the general formula \(RCOOH\)) and an alcohol (with the general formula \(R'OH\)). The reaction is called esterification, and the general formula of an ester is \(RCOOR'\). In this formula, \(R\) in the carboxylic - acid part can be \(H\) (for formic acid, \(HCOOH\)), an alkyl group (e.g., \(CH_3CH_2COOH\) - propanoic acid), or an aryl group (e.g., \(C_6H_5COOH\) - benzoic acid). The \(R'\) group comes from the alcohol part. Alcohols can be alkyl - based (e.g., \(CH_3OH\) - methanol, \(C_2H_5OH\) - ethanol) or aryl - based (e.g., \(C_6H_5OH\) - phenol). But \(R'\) cannot be a hydrogen atom. If \(R'\) were \(H\), the formula \(RCOOR'\) would be \(RCOOH\) (a carboxylic acid), not an ester.

Answer:

False
