GEOLOGY

Detailed explanation-1: -Single bond is defined as the chemical bond between two atoms and has two valence electrons. The number of sigma bonds present in the single bond is only one. The number of pi bonds present in a single bond is zero.

Detailed explanation-2: -Oxygen can form only two bonds because it requires two electrons to complete its octet after which it will not have any more vacant orbitals left to accept more electrons and form more bonds.

Detailed explanation-3: -Why does C2 molecule have 2 pi bonds and no sigma bonds.

Detailed explanation-4: -O2 has one bond and one bond. Was this answer helpful?

Detailed explanation-5: -Multiple bonds Two pi bonds are the maximum that can exist between a given pair of atoms. Quadruple bonds are extremely rare and can be formed only between transition metal atoms, and consist of one sigma bond, two pi bonds and one delta bond.
