Sigma and Pi Bonds

Postby Emily Orozco L4 » Sun Nov 25, 2018 11:49 pm

Which bond allows bound atoms to rotate?

Sigma bonds allow atoms to rotate freely, unlike pi bonds.

Sigma bonds allow for free rotation of atoms. With pi bonds the whole molecule has to rotate, and single atoms cannot rotate freely.

Since sigma bonds have one point of connectivity between two atoms, these atoms are allowed to freely rotate. If a pi bond forms, there would be two points of contact between atoms, preventing the atoms from rotating.
