Question

The mass of benzanilide obtained from the benzoylation reaction of 5.8 g of aniline, if yield of product is 82 \%, is \_ \_ \_ \_ g (nearest integer). (Given molar mass in gmol^-1H :1 ,C :12 , N :14 ,O :16 )

Accepted Answer

Correct answer: 10. (10) Benzoylation of aniline: C_6H_5 NH_2+C_6H_5 COCl C_6H_5 CONHC_6H_5+ HCl Molar mass of aniline: M=6 (12 )+7 (1 )+14=93 g/ mol Moles of aniline: n= 5.893=0.0624 mol Molar mass of benzanilide ( C_13H_11 NO ): M=13 (12 )+11 (1 )+14+16=197 g/ mol Theoretical mass of benzanilide: m_ theoretical=0.0624 197=12.29 g Actual mass with 82 \% yield: m_ actual=12.29 0.82=10.08 ≈10 g

$The mass of benzanilide obtained from the benzoylation reaction of 5.8 g of aniline, if yield of product is 82 %, is____g (nearest integer). (Given molar mass in gmol^{- 1} H : 1, C : 12, N : 14, O : 16)$
