Question

The hybridisation of molecule C2H4 AND PCl5 are.

a) SP3 and SP2 b) SP and SP3. C) SP2 and SP3d.​

Answer 1

Answer:

Let us look at how the hybridization of ethene (ethylene) occurs. When we look at the molecules of C2H4 it has 2 CH molecules and 4 H molecules. The carbon atom consists of 6 electrons and hydrogen has 1 electron.

During the formation of CH2=CH2, the electronic configuration of carbon in its ground state (1s2 2s2 2p1 2p1) will change to an excited state and change to 1s2 2s1 2px12py1 2pz1. In the excited state, since carbon needs electrons to form bonds one of the electrons from 2s2 orbital will be shifted to the empty 2pz orbital to give 4 unpaired electrons.
