Question

What is the hybridisation of C2H4​

Answer 1

Explanation:

sp2 Hybridisation in Ethene (C2H4):

This is similar to sp3 hybridisation, except there are only 2 hydrogen nuclei pulling on the bonding electrons (which need an electron each) and the other 2 electrons are required for the π (pi) bond (double bond) between the two Carbons.

Answer 2

IN C2H4 on each carbon there are 3 sigma bonds one pie bond and 0 lone pair therefore the electron domain is 3 as hybridization is sp2
