Question

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

- Primary

- Tertiary

- Secondary

Answer 1

Answer: Option (b) is the correct answer.

Step-by-step 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.

Answer 2

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.
