Question

A _______ alcohol has a -OH radical bonded to a central carbon atom.

- Primary

- Tertiary

- Secondary

Answer 1

A  tertiary   alcohol  has  the OH-  radical  bonded to the central  carbon atom


A tertiary  alcohol  is  a  alcohol by which  by   which  hydroxy  group  (OH-) is attached to a  saturated  carbon  atom  which  has other three carbon  atoms  to it.   This make  the  carbon  in which  hydroxy is attached  a central   carbon since  it  has   four group  attached to it.

Answer 2

Answer: Option (b) is the correct answer.

Explanation:

A hydrocarbon chain that contains a functional group "-OH" is known as an alcohol.

When "-OH" group is attached at the first carbon of a hydrocarbon then it is known as primary alcohol. For example, $CH_{3}CH_{2}CH_{2}OH$ is propanol and it is a primary alcohol.

When "-OH" group is attached at the second carbon of a hydrocarbon then it is known as primary alcohol. For example, $CH_{3}CH_{2}CH_{2}OHCH_{3}$ is 2-butanol and it is a secondary alcohol.

When "-OH" group is attached at the central carbon of a hydrocarbon then it is known as tertiary alcohol. For example, $(CH_{3})_{3}C(OH)$ is 1,1-Dimethylethanol and it is a tertiary alcohol.

Therefore, we can conclude that a tertiary has a -OH radical bonded to a central carbon atom.
