MCQ
In R−X the bond length is maximum in:
  • A
    C−F
  • B
    C−Cl
  • C
    C−Br
  • D
    C−I

Answer

  1. 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.
