Vedclass · Answer

(D) secondary $(2^o)$ alcohol is one in which the hydroxyl $(-OH)$ group is attached to a carbon atom that is bonded to two other carbon atoms.Analyzing the structures:$(I)$ The $-OH$ group is on a primary carbon. (Not $2^o$)$(II)$ The $-OH$ group is on a tertiary carbon. (Not $2^o$)$(III)$ The $-OH$ group is on a secondary carbon. ($2^o$ alcohol)$(IV)$ The $-OH$ group is on a primary carbon. (Not $2^o$)$(V)$ The $-OH$ group is on a tertiary carbon. (Not $2^o$)$(VI)$ The $-OH$ group is on a primary carbon. (Not $2^o$)Wait,re-evaluating the structures:$(I)$ $CH_3CH_2CH(OH)CH_2OH$: The $-OH$ at the $3^{rd}$ position is secondary.$(III)$ $CH_3CH_2CH(OH)CHO$: The $-OH$ is on a secondary carbon.$(V)$ $CH_3CH_2C(OH)(CH_3)CH(OH)CH_3$: The $-OH$ at the $4^{th}$ position is secondary.Thus,compounds $(I, III, V)$ contain at least one secondary alcohol group. The correct option is $(D)$.

Which of the following compounds contain at least one secondary $(2^o)$ alcohol?
