Question

A compound x with molar mass 108g mol^(−1) undergoes acetylation to give product with molar mass 192g mol^(−1). The number of amino groups in the compound x is ________.

MARKS Content Team · Accepted Answer

Correct answer: 2. The compounds like amines and alcohols undergo acetylation with acetyl chloride. During this reaction, one proton of amine or alcohol is replaced with one acetyl group(CH_3CO-). The molar mass of the acetyl group is 43 g/mol. The increase in molar mass due to one acetyl group is 43-1=42g/mol. The molar mass of reactant is 108 g/mol. The molar mass of product is 192 g/mol. The change in mass is 84. Hence, the number of acetyl groups =84/42=2

A compound $(x)$ with molar mass $108 g {mol}^{- 1}$ undergoes acetylation to give product with molar mass $192 g {mol}^{- 1}$ . The number of amino groups in the compound $(x)$ is ________.
