MCQ
In R−X the bond length is maximum in:
- AC−F
- BC−Cl
- CC−Br
- DC−I
✓
Answer
- C−I
Explanation:
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.
