The hybridisation of Carbon in ethylene is:

The hybridisation of carbon in ethylene is sp².

Explanation

Ethylene or Ethene is a compound with the formula C₂H₄.

• The molecule contains 2 carbon atoms and 4 hydrogen atoms.
• The molecules comprises of a double bond.
• The carbon atom consists of 6 electrons and hydrogen has 1 electron.
• The carbon atom consists of 6 electrons and hydrogen has 1 electron.

Hence in the ethene molecule, the carbon atoms are sp² hybridized. One unpaired electron in the p orbital remains unchanged. Each carbon combines with three other atoms rather than four.
