Question

Bond between $A$ and $B$ can be represented by
$\underset{(I)}{A-B}\underset{(II)}{A^{+}{B}^{-}}\underset{(III)}{A^{-}{B}^{+}}$
If $A$ is more electronegative than $B$, then least contribution to the actual structure comes from

• A. I
• B. II
• C. III
• D. All the structures have equal contribution

Answer 1

Answer: (B)

Structure $II$ shows A to be electropositive Hence, It will have least contribution.
