Which of the following statement is incorrect?

Options

A. The tendency to attract bonded pair of electron in case of hybrid orbitals follow the order : `sp gt sp^(2) gt sp^(3)`
B. Alkali metals generally have negative value of electron gain enthalpy.
C. `Cs^(+)(g)` release more energy upon gain of en electron than `CI(g)`.
D. The electronegativity values for `2p`-series elements is less than that for `3p`-series elements on account of small size and high inter electronic repulsions.

Answer

D

Explanation

The tendency of attract bonded pair of electron in case of hybrid orbitals increases with increase in `%s`. Character and so the order : `sp gt sp^(2) gt sp^(3)`
The electron affinity values for `2p`-series elements is less that for `3p`-series elements on account of small size and high inter electronic repulsions. statements `(B)` and `(C )` are facts. Every cation releases more energy than neutral atom upon gain of an electrons.
