Text solutionVerified

The acylation of an amine group can be represented as:

RN H_{2} + C H_{3} COCl \to RN H COC H C H_{3} + H Cl

Molecular mass of the compound

= 180 u

Molecular mass of the product

= 390 u

Increase in molecular mass of the product

= 390 - 180 = 210 u

Since in acylation, one

H

group per

N H_{2}

is replaced by one

COC H_{3}

group.
Hence, Mass of

COC H_{3} = 43 u

Mass of

H = 1 u

Mass added per

N H_{2}

group

= 42 u

Hence number of amino groups

= \frac{210}{42} = 5
