Vedclass · Answer

(B) primary alcohol is one in which the $-OH$ group is attached to a primary carbon atom (a carbon atom bonded to only one other carbon atom).$1$. Butan-$1$-ol $(CH_3CH_2CH_2CH_2OH)$: The $-OH$ group is attached to a terminal carbon,which is bonded to only one other carbon. Thus,it is a primary alcohol.$2$. Butan-$2$-ol $(CH_3CH(OH)CH_2CH_3)$: The $-OH$ group is attached to a carbon bonded to two other carbons. Thus,it is a secondary alcohol.$3$. Propan-$2$-ol (Isopropyl alcohol) $(CH_3CH(OH)CH_3)$: The $-OH$ group is attached to a carbon bonded to two other carbons. Thus,it is a secondary alcohol.Therefore,butan-$1$-ol is the primary alcohol.
