Sigma and Pi Bonds

How are sigma bonds formed?

• By the electrostatic attraction between positive ions and delocalised electrons

• By direct overlap of orbitals between the bonding of atoms

• By sideways overlap of orbitals

• By the electrostatic attraction between oppositely charged ions

How many pi bonds does this picture have?

• 0

• 3

• 5

• 10

• By direct overlap of orbitals between the bonding of atoms

• By the electrostatic attraction between positive ions and delocalised electrons

• By the electrostatic attraction between oppositely charged ions

Why is sigma bond stronger than pi bond?

• It has high level of attraction between oppositely charged ions

• It has mobile electrons

• The overlapping in sigma bond is minimum

• It has high level of attraction between nuclei and shared electrons
