Butan-2-ol is an example of -

Answer 1

Alcohol

• Alcohols are formed when a hydrogen atom in a hydrocarbon, aliphatic and aromatic respectively, is replaced by $\text{-OH}$ group.
• It can be classified as primary, secondary, and tertiary alcohol.

Butan-2-ol

• The structure of Butan-2-ol is as follows:-
• $$\begin{gathered} {\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{CH}\left(\mathrm{OH}\right)-{\mathrm{CH}}_3 \\ 4321 \end{gathered}$$
• In the above structure, $\text{-OH}$ group is attached to a saturated carbon atom which has two other carbon atoms attached to it.
• Hence, Butan-2-ol is an example of a secondary alcohol.
