Question

1. What is the number of unhybridised orbitals in
ethylene.​

Answer 1

 In the formation of ethene molecule, there are 2 C atoms and 4 H atoms. - 3 orbitals of each carbon atom undergo sp2 hybridisation and 1 orbital remains unhybridised. - Each H atom has 1 unhybrid orbital. - So there are total 6 unhybrid orbital and 6 sp2 hybrid orbitals
