Question

Which of the following is the correct method of
preparation of methyl fluoride?
(a) CH₄ + HF → (b) CH₃OH + HF →
(c) CH₄ + F₂ → (d) CH₃Br + AgF →

Answer 1

Explanation:

option d is the correct answer

Answer 2

The correct method of  preparation of methyl fluoride is

(d) CH₃Br + AgF →

According to Swarts reaction, alkyl flourides can be prepared by reacting the same alkyl bromide or chloride solution with AgF solution.

The reaction which happens is shown below.

CH₃Br + AgF → CH₃F + AgBr

In this way, the required methyl flouride is produced.

So, option (d) is the correct answer.
