In which of the following compounds, -OH is the functional group?
(a) Butanone
(b) Butanol
(c) Butanoic
(d) Butanal.

Academic Chemistry NCERT Class 10

Correct Answer: (b) Butanol

Explanation: The general formula of alcohols is C_nH_2n+1— OH.

For butanol, n = 4. So, formula is

C₄H₉—OH or

CH₃—CH₂—CH₂—CH₂—OH
