MCQ
In $R−X$ the bond length is maximum in:
- A$C−F$
- B$C−Cl$
- C$C−Br$
- ✓$C−I$
✓
Answer
Correct option: D.
$C−I$
As we progress down the periodic table from fluorine to iodine, molecular size increases.
As a result, we also see an increase in bond length. Conversely, as molecular size increases and we get longer bonds, the strength of those bonds decreases.
