Question

Electronegativity does not depend on hybridized state.

• A. True
• B. False

Answer 1

The correct option is B

False

Electronegativity increases as s-character increase. Do you wonder why?
Lets find out.
Hybridized state: s-electrons are more penetrated than p-electron towards the nucleus. Therefore, if an atom has hybrid orbitals with greater $s^{-}$ character the electronic charge in such orbitals will remain more closer to the nucleus of that atom. Thus electonegativity of such atom will be higher.
For example:
$C{H}_4$ ${sp}^3$ $25\%$ s - character
$C_2{H}_4$ ${sp}^2$ $33\%$ s - character
$C_2{H}_2$ sp $50\%$ s - character
