Vedclass · Answer

(B) An aldehyde is represented by the general formula $R-CHO$,where $R$ is an alkyl group or a hydrogen atom.In $Methanal$ $(HCHO)$,the $R$ group is replaced by a hydrogen atom $(H)$.Therefore,$Methanal$ is the only aldehyde that does not contain an alkyl group attached to the carbonyl carbon.$Methanol$ is an alcohol,not an aldehyde.$Ethanal$ $(CH_3CHO)$ contains a methyl group $(CH_3)$,and $Propanal$ $(CH_3CH_2CHO)$ contains an ethyl group $(CH_3CH_2)$.

Which aldehyde compound does not contain an alkyl group?
