An organic compound (P) having molecular mass 180 is acylated with C H 3 C O C l to get a new compound with molecular mass 348. The number of amino groups present per molecule of compound (P) is

Correct answer

4

Step-by-step solution

R − NH 2 M + CH 3 COCl → RNHCOCH 3 M + 42 + HCl If the increase in molecular mass is 42, the reactant has one N H 2 group. Actual increase in molecular mass = 348 - 180 = 168 Number of N H 2 groups = 168 42 = 4
