o ch3 - ch - ch2 - ch3

Explanation:

A secondary alcohol has the hydroxyl (-OH) group attached to a carbon atom that is bonded to two other carbon atoms. In propan - 1 - ol (\(CH_3CH_2CH_2OH\)), the - OH group is attached to a carbon (the first carbon) that is bonded to only one other carbon atom (the second carbon). In propan - 2 - ol (\(CH_3CH(OH)CH_3\)), the - OH group is attached to a carbon that is bonded to two other carbon atoms.

Answer:

\(CH_3 - CH_2 - CH_2 - OH\) (propan - 1 - ol)
