A carbon, hydrogen and oxygen atoms containing organic compound (A), on reaction with an excess of CH3MgI, gives a gas (X) whose volume under STP conditions is found to be 89.6litre. Find the number of hydroxyl groups in the compound (A):
Correct answer: D. 4
- A. 3
- B. 5
- C. 2
- D. 4
Explanation
When a compound containing carbon, hydrogen, and oxygen atoms reacts with CH3MgI to produce a gas with a volume of 89.6 liters under STP conditions, it indicates the presence of 4 hydroxyl groups in the compound. The reaction involves the conversion of the oxygen in the compound to a hydroxyl group, leading to the formation of the gas. Options A, B, and C do not consider the correct stoichiometry of the reaction and the volume of gas produced, leading to incorrect answers.
