Explain, how is the electronegativity of carbon atoms related to the state of hybridisation in an organic compound ?

Explanation

Electrongeativity of carbonn atom, also depends on the hybidisation of the carbon atom. Since, s-electrons are more strongly attracted by the nucleus than p-electons, thus, electronegativity increases with increase in s-character of the hybridised orbital i.e.,
`underset(sp^(3) lt sp^(2) lt sp)overset(25% 33.3% 50%)rarr` Hybridisation
`underset(underset("of electronegativity")("Increasing order"))overset(overset("Increasing order")("of % s-character"))rarr`
Thus, sp-hybridised carbon is the most electronegative carbon
