ChemistrySingle correct+4 / -1Question 65 of 75

Given below are two statements:

Statement I: Methane can be prepared by decarboxylation of sodium ethanoate, Kolbe's electrolysis of sodium acetate and reaction of $\ce{CH3MgBr}$ with water.

Statement II: Methane cannot be prepared from unsaturated hydrocarbons and by Wurtz reaction.

In the light of the above statements, choose the correct answer from the options given below

Both Statement I and Statement II are true

Both Statement I and Statement II are false

Statement I is true but Statement II is false

Statement I is false but Statement II is true

Answer and worked solution

Official answer: D

Statement I. Decarboxylation of sodium ethanoate and the hydrolysis of $\ce{CH3MgBr}$ both give methane. But Kolbe electrolysis of sodium acetate gives ethane. False.

Statement II. Methane has one carbon. Hydrogenating an unsaturated hydrocarbon gives at least ethane, and Wurtz coupling gives at least ethane. True.

(D)
