Assertion (A) :F atom has less electron than `CI^(Theta)` atom
Reason (R ) : Additional electrons are repelled more effectively by `3p` electron in `CI` atom than by` 2p` electron in F atom

A

Statement I is true: Statement II is true, Statement II is the correct explanation of Statement I.

B

Statement I is true, Statement II is true, Statement II is not the correct explanation of Statement I.

C

Statement I is true, Statement II is false.

D

Statement I is false, Statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
C
Statement I is true, Statement II is false.
`F` atom has slightly lower affinity for the electron than chlorine.
It is due to the reason that additional electrons are repelled more effectively by `2p`- electrons in `F` than by `3p`- electrons in `Cl`-atom.
