Question

An aromatic compound (X) $\left( \mathrm { C } _ { 8 } \mathrm { H } _ { 8 } \mathrm { O } \right)$gives positive 2,4- DNP test. It gives a yellow precipitate of compound (Y) on reaction with iodine and sodium hydroxide solution (X) does not give Tollen’s test on oxidation acid (Z) $\mathrm { C } _ { 7 } \mathrm { H } _ { 6 } \mathrm { O } _ { 2 }$.(Z) is also formed with (Y) during the reaction. (X) (Y) and (Z) respectively are.

• A. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { COCH } _ { 3 } , \mathrm { CHI } _ { 3 } , \mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { COOH }$
• B. $\mathrm { CH } _ { 3 } \mathrm { COCH } _ { 3 } , \mathrm { CHI } _ { 3 } , \mathrm { CH } _ { 3 } \mathrm { COOH }$
• C. $\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { COCH } _ { 3 } , \mathrm { CHI } _ { 3 } , \mathrm { CH } _ { 3 } \mathrm { COOH }$
• D. $\mathrm { CH } _ { 3 } \mathrm { CHO } , \mathrm { CHI } , \mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { COOH }$

Answer 1

Answer: (A)

$\mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { COCH } _ { 3 } , \mathrm { CHI } _ { 3 } , \mathrm { C } _ { 6 } \mathrm { H } _ { 5 } \mathrm { COOH }$
