Tardigrade Admin · Accepted Answer

Four isomeric amines are possible having C 3 H 9 N formula: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/c24c71b6ea8b24bea9dbed13b90a5ca4-.png" /> Hoffmann's isocyanide test is not given 2° and 3° amines. Therefore, two structural isomers having C 3 H 9 N formula will NOT give Hoffmann's isocyanide test.

Q. How many structural isomers having $C_{3} H_{9} N$ formula will NOT give Hoffmann's isocyanide test?

Four isomeric amines are possible having $C_{3} H_{9} N$ formula:

Hoffmann's isocyanide test is not given $2^{\circ}$ and $3^{\circ}$ amines.
Therefore, two structural isomers having $C_{3} H_{9} N$ formula will NOT give Hoffmann's isocyanide test.

Q. How many structural isomers having C3​H9​N formula will NOT give Hoffmann's isocyanide test?

Four isomeric amines are possible having C3​H9​N formula: Hoffmann's isocyanide test is not given 2∘ and 3∘ amines. Therefore, two structural isomers having C3​H9​N formula will NOT give Hoffmann's isocyanide test.
