$3-$pentanone

Vedclass · Answer

(A) The haloform reaction is given by compounds containing the $CH_3CO-$ group or compounds that can be oxidized to this group (e.g.,secondary alcohols with the $CH_3CH(OH)-$ group).$1$. $3-$pentanone is $CH_3CH_2COCH_2CH_3$. It does not contain the $CH_3CO-$ group,so it does not give the haloform reaction.$2$. $1-$phenylethanol is $C_6H_5CH(OH)CH_3$. It contains the $CH_3CH(OH)-$ group,which can be oxidized to the $CH_3CO-$ group,so it gives a positive haloform test.$3$. $3-$methylbutan$-2-$ol is $(CH_3)_2CHCH(OH)CH_3$. It contains the $CH_3CH(OH)-$ group,so it gives a positive haloform test.$4$. Acetophenone is $C_6H_5COCH_3$. It contains the $CH_3CO-$ group,so it gives a positive haloform test.Therefore,$3-$pentanone does not show the haloform reaction.
