MCQ
$C−X$ bond is strongest in:
- A$\mathrm{CH}_3 \mathrm{Cl}$
- B$\mathrm{CH}_3 \mathrm{Br}$
- ✓$\mathrm{CH}_3 \mathrm{~F}$
- D$\mathrm{CH}_3 \mathrm{I}$
✓
Answer
Correct option: C.
$\mathrm{CH}_3 \mathrm{~F}$
The carbon$-$halogen bonds $($apart from the carbon$-$iodine bond$)$ are polar, because the electron pair is pulled closer to the halogen atom than the carbon.
This is because $($apart from iodine$)$ the halogens are more electronegative than carbon. The Carbon$-$Fluorine bond is strongest.
