A compound with molecular mass \(180\) is acylated with \(CH_3COCl\) to get a compound with molecular mass \(390.\) The number of amino groups present per molecule of the former compound is :
- A \(2\)
- B \(5\)
- C \(4\)
- D \(6\)
Answer & Solution
Correct Answer
(B) \(5\)
Step-by-step Solution
Detailed explanation
During acetylation, one \(H\) atom with atomic mass \(1\,amu\) of \(- NH_2\) group is replaced by an acetyl group \(\mathrm{CH}_{3} \mathrm{CO}[\text { molecular mass }=434 \,\mu ]\). Thus…
