Question

29) Methyl magnesium bromide on hydrolysis gives
A. Ethane
B. Methane
C. Propane
D. Butane

Answer 1

Answer:

butane it will give butane .

Answer 2

The correct option is B.

• Methyl magnesium bromide is also called Grignard reagent. It is used in many reactions.
• On hydrolysis with water, methyl magnesium bromide gives methane MgBr(OH).
• The balanced reaction is as follows-
• $CH_3MgBr+H_2O\rightarrow CH_4+MgBr(OH)$.
• In this reaction, one mole of methyl magnesium bromide reacts with one mole of water to form one mole of methane along with one mole of MgBr(OH).
• Hence the product is methane.
