Question

making use of concept of hybridization discuss the shape of C2 H4 molecule

Answer 1

hybridization of C2H4 is sp2 nd structure is given below. in the excited state the electron form 2s orbital of C go to 2p orbitalforming 4 half filled atomic orbital. since each C is joining to 3 other atoms instead of 4 the C hybridizes their 3 outer orbital instead of 4 so it use 2s & 2p electron leaving on 2p electron unchanged. thereby forming sp2 hybridization
its structure is triangular planar having bond angle of 120 degree.
