w/ one sigma bond, they could rotate around the axis - the addition of pi bonds (by a leftover p structure) makes this carbon-carbon double bond rigid. you can't have the molecule flipping without the other one have to switch - so basically, the molecule's now on lockdown.

Covalent Bonds And Electrons

Covalent bonds- A covalent bond is a chemical bond that involves sharing electron pairs between atoms. The balance of positive and negative forces between atoms when they share electrons is known as covalent bonding

Sigma and Pi Bonds: Hybridization Explained!

Sigma bonds are the FIRST bonds to be made between two atoms. They are made from hybridized orbitals. Pi bonds are the SECOND and THIRD bonds to be made.
