• A. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { SO } _ { 2 } \mathrm { Cl }$
• B. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { SO } _ { 3 } \mathrm { H }$
• C. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { NHCH } _ { 3 }$
• D. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { COCH } _ { 3 }$

Answer 1

Answer: (A)

$\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { SO } _ { 2 } \mathrm { Cl }$

Answer 2

: Benzenesulphonyl chloride $\left( \mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { SO } _ { 2 } \mathrm { Cl } \right)$ acts as Hinsberg’s reagent.
