MCQ
Compound that will give positive Lassaigne's test for both nitrogen and halogen is
- A$N _2 H _4 \cdot HCl$
- ✓$CH _3 NH _2 \cdot HCl$
- C$NH _4 Cl$
- D$NH _2 OH . HCl$
✓
Answer
Correct option: B.
$CH _3 NH _2 \cdot HCl$
b
$CH _3 NH _2 . HCl \underset{\text { fusion }}{\stackrel{ Na }{\longrightarrow}} NaCN$ and $NaCl$
$CH _3 NH _2 . HCl \underset{\text { fusion }}{\stackrel{ Na }{\longrightarrow}} NaCN$ and $NaCl$
$NaCN$ gives $+ve$ test for nitrogen and
$NaCl$ gives $+ve$ test for halogen
