Question

Methane and ethane both can be obtained in single step from.

• A. $CH_{3}I$
• B. $C_{2}H_{5}I$
• C. $CH_{3}OH$
• D. $C_{2}H_{5}OH$

Answer 1

Answer: (A)

$CH_{3}I$

Answer 2

$CH_{3}I + 2H\overset{\quad Zn/HCl\quad}{\rightarrow}CH_{4} + HI$

$CH_{3}I + 2Na + ICH_{3}\underset{\text{Ether}}{\overset{\quad\text{Dry}\quad}{\rightarrow}}CH_{3} - CH_{3} + 2NaI$
