RMgI when treated with ice cold water liberated a gas which occupied 1.4 dm³/g at STP. The gas produced is further reacted with iodine in presence of HIO₃ to give compound (X). Compound (X) in presence of Na and dry ether produced compound (Y). Molar mass of compound (Y) is g mol⁻¹. (Nearest integer)

Answer: 30

Solution

Molar mass of the gas = 22.4/1.4 = 16 g/mol → CH₄ (so R=CH₃). CH₄+I₂/HIO₃
