MCQ
Which alky halide has maximum density?
- A$\mathrm{C}_3 \mathrm{H}_7 \mathrm{F}$
- B$\mathrm{C}_2 \mathrm{H}_5 \mathrm{Cl}$
- C$\mathrm{CH}_3 \mathrm{Br}$
- ✓$\mathrm{CH}_3 \mathrm{I}$
✓
Answer
Correct option: D.
$\mathrm{CH}_3 \mathrm{I}$
$\mathrm{CH}_3 \mathrm{I}$ has the highest molecular weight hence, it is alkyl halide with maximum density$.(Mol. wt.$ of $\mathrm{CH}_3 \mathrm{I}) = (Mol. wt.$ of $C) + 3 \times (Mol. wt.$ of $H) + (Mol. wt$. of $I)$
$= 12 + (3 \times 1) + 127$
$= 42$
$= 12 + (3 \times 1) + 127$
$= 42$
