Chemical bonding (Hybridisation)

Two carbon atoms form a linear shaped ethene, C₂H₄, molecule when bonded with four other hydrogen atoms. Prior to bonding, the carbon atom

• does not hybridise

• undergoes sp hybridisation

• undergoes sp² hybridisation

• undergoes sp³ hybridisation

The molecule that uses sp³d hybrid orbital on the central atom is
