The compound from which formic acid cannot be prepared is

Options

  1. Amethyl alcohol
  2. Bcarbon monoxide + NaOH
  3. Cglycerol
  4. Dmethyl magnesium bromide

Correct answer

D. methyl magnesium bromide

Step-by-step solution

Formic acid (HCOOH) cannot be prepared from methyl magnesium bromide ( CH ₃ MgBr ) while from all other reagents, it is obtained as (a) CH ₃ OH [ O ] HCHO [ O ] HCOOH methyl alcohol (b) CO + NaOH HCOONa NaHSO ₄ HCOOH + Na ₂ SO ₄ (c) Glycerol + Oxalic acid 383 ~K H ₂ O HCOOH + glycerol
