In ethylene, how many unhybridized p-orbitals are present?

ایتھیلین میں، کتنے غیر ہائبرڈائزڈ پی - مدار موجود ہیں؟

None of these

In ethylene ( $C_2H_4$ ), each carbon atom undergoes $sp^2$ hybridization, leaving one unhybridized p-orbital per carbon atom.

These two unhybridized p-orbitals overlap to form the $pi$ -bond in the double bond.
