Question

Total number of isomeric alcohols with formula $C _{4} H _{10} O$ is

• A. -2
• B. 1
• C. 3
• D. 4

Answer 1

Answer: (D)

Possible isomers are

$CH _{3} CH _{2} CH _{2} CH _{2} OH \,\,\,\,$ $n$ -butyl alcohol

$CH _{3}- \underset{\underset{CH_3}{|}}{CH} - CH _{2}- OH \,\,\,\,$ iso-butyl alcohol

$CH _{3}- CH _{2}- \underset{\underset{OH}{|}}{CH} - CH _{3}\,\,\,\,$ sec. butyl alcohol

$CH_3 - \underset{\overset{|}{C}H_3}{\overset{\underset{|}{C}H_3}{C}} - OH\,\,\,$ tert. butyl alcohol
