Options

  1. AWhich of the following combinations will produce H _ 2 gas?
  2. BWhich of the following combinations will produce H _ 2 gas?
  3. CWhich of the following combinations will produce H _ 2 gas?
  4. DWhich of the following combinations will produce H _ 2 gas?

Correct answer

D. Which of the following combinations will produce H _ 2 gas?

Step-by-step solution

The isomers of C8H11N{C}_{8}{H}_{11}N, that can be prepared by Gabriel phthalimide synthesis are primary amines.

Isomeric amines with molecular formula C _ 8 H _ 11 N give the following tests Isomer (P) ⇒ Can be prepared by Gabriel

can be prepared by Gabriel phthalimide synthesis because SN2{S}_{N}2 is possible in

Isomeric amines with molecular formula C _ 8 H _ 11 N give the following tests Isomer (P) ⇒ Can be prepared by Gabriel

Secondary amines react with Hinsberg’s reagent to give solid insoluble in NaOHNaOH. Hence, Q is the secondary amine

Isomeric amines with molecular formula C _ 8 H _ 11 N give the following tests Isomer (P) ⇒ Can be prepared by Gabriel

Aromatic amines like aniline give diazonium salts. The diazonium salt used in diazo coupling to get red dye with beta Naphthol in sodium hydroxide. Hence, R is aromatic amine as shown below.

Isomeric amines with molecular formula C _ 8 H _ 11 N give the following tests Isomer (P) ⇒ Can be prepared by Gabriel
