Question

Which of he following is a secondary alkanol?

a. CH3CH2CH2OH
b. CH3CH2CH2CH2OH
c. C(CH3)3OH
d. CH3CH(OH)CH3

Answer 1

Answer: Thus
`CH_3CH(OH)CH_3` is a secondary alkanol.

Step-by-step explanation:

Alkanol are compounds which contains carbons bonded by single bonds and contains hydroxy (-OH) as functional group.

Primary alkanol are those compounds which contain hydroxyl group attached a carbon which is further attached to a single carbon atom. Example:
`CH_3CH_2CH_2OH` and
`CH_3CH_2CH_2CH_2OH`

Secondary alkanol are those compounds which contain hydroxyl group attached to a carbon which is further attached to two more carbon atoms.Example:
`CH_3CH(OH)CH_3`

Tertiary alkanol are those compounds which contain hydroxyl group attached to a carbon which is further attached to three more carbon atoms. Example:
`C(CH_3)_3OH`

Thus
`CH_3CH(OH)CH_3` is a secondary alkanol.
