MCQ
A hydrocarbon contian $80\%\,C$. The vapour density of compound in $30$. Molecular formula of compound is :-
- A$CH_3$
- B$C_2H_6$
- ✓$C_4H_{12}$
- DAll of these
✓
Answer
Correct option: C.
$C_4H_{12}$
c
mol. mass $= 2 \times$ vapour density
$= 2 \times 30 = 60$
mol. mass $= 2 \times$ vapour density
$= 2 \times 30 = 60$
