Text Solution

Verified by Experts

The correct Answer is:
A
Molecular mass of compound =180
Molecular mass after acetylation =390
Increases in molecular mass =210
`R-NH_(2)+CH_(3)-overset(O)overset(||)(C) -Cl to`
`R-NH-overset(O)overset(||)(C)-Me` Increase in molecular mass for one` -NH_(2)` is 42 so total amino groups are
present.
