Question

In the reaction

$CH_3-CH_2-OH$ $\ce{ ->[(i)TsCl][(ii) LiAlH_4] X}$

, (X) will be

• A. $CH_{2}=CH_{2}$
• B. $CH_{3}-CH_{2}-CH_{2}-CH_{3}$
• C. $CH_{3}-CH_{3}$
• D. $CH_{3}-CH=CH-CH_{3}$

Answer 1

Answer: (A)

Here the compound X is ethane and formed as follows

$CH _{3}- CH _{2}- OH \stackrel{ TsCl }{\longrightarrow } CH _{3}- CH _{2}- OTs \stackrel{ LiAlH _{4}}{\longrightarrow } CH _{3}- CH _{3}$

Hint : It involves substitution followed by reduction.
