Question

Why is it said that a `sp^2` hybridized carbon more electronegative than a `sp^3` hybridized carbon?

Answer 1

See the answer below....

Explanation:

The carbon which has more `color(red)s` character,the atom is more electronegative.

Let's calculate `color(red)s` character in `sp^2` and `sp^3` hybridized atom.

In case of `sp^2` hybridization, the number of `s` orbital is `1` where total number of orbital is `1+2=3`. Means `s` character is `1/3xx100%=33.33%`

In case of `sp^3` hybridization, the number of `s` orbital is `1` where number of total orbital is `1+3=4`. Hence, `s` character is `1/4×100%=25%`.

So,`sp^2` hybridized atom is more electronegative than `sp^3` hybridized atom.

Hope it helps...
