CH 3 NH 2 . HCl xrightarrow[ text fusion ] Na NaCN and NaCl NaCN gives + ve test for nitrogen and NaCl gives +ve test for halogen

Q. Compound that will give positive Lassaigne's test for both nitrogen and halogen is:

$N H_{2} O H . H Cl$

$C H_{3} N H_{2} \cdot H Cl$

$N H_{4} Cl$

$N_{2} H_{4} \cdot H Cl$

$C H_{3} N H_{2} . H Cl N a fusion N a CN$ and $N a Cl$
$N a CN$ gives $+ v e$ test for nitrogen and
$N a Cl$ gives +ve test for halogen
