A 100 mL solution of CH3CH2MgBr on treatment with methanol produces 2.24 mL of a gas at STP. The weight of gas produced is _____________ mg. [nearest integer]

Step-by-Step Verified Solution

CH3−CH2−MgBr+CH3OH→CH3−CH3+MgBr(OCH3)

As 2.24ml is formed at STP.

Number of moles of ethane gas produced

=2.24X22.4

=10−4ml

Mass of ethane produced =10−4×30=3×10−=3mg
