Show Answer
Answer:
Correct Answer: A
Solution:
$ \underset{CH_2}{\overset{CH_2}{\mathop{||}}}+H_2SO_4\to \underset{CH_2HSO_4}{\overset{CH_3}{\mathop{|}}}\xrightarrow{H_2O} $
$ \underset{CH_2OH}{\overset{CH_3}{\mathop{|}}}+H_2SO_4 $ Except ethyl alcohol, no other primary alcohol can be prepared by this method as the addition of $ H_2SO_4 $ follows Markownikoff’s rule.
Generally secondary and tertiary alcohols are obtained.
