Options
- Amethyl alcohol
- Bcarbon monoxide + NaOH
- Cglycerol
- 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
