Question

Assertion : Heterolytic fission occurs readily in polar covalent bonds.
Reason : Heterolytic fission involves breaking of bond in such a way that the shared pair of electrons go with one atom.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are true false

Answer 1

Answer: (B)

In polar covalent bond, shared pair of electrons is displaced towards the more electronegative atom and hence in heterolytic fission, the electron pair is easily taken away by more electronegative atom.
