Question

How many litres of gas $P$ is formed in above reaction at $NTP$ ?
(molar volume of gas at $NTP$ is $22.4 \, L$ )

• A. $22.4 \, L$
• B. $33.6 \, L$
• C. $44.8 \, L$
• D. $66 \, L$

Answer 1

Answer: (C)

Grignard's reagent reacts with acidic-H to release methane

Volume of $CH_{4}$ at $NTP \, =2\times $ molar volume
$=2\times 22.4=44.8 \, L$
