Question

define Sigma bond and pi bond
​

Answer 1

Answer:

Sigma and pi bonds are types of covalent bonds that differ in the overlapping of atomic orbitals. Covalent bonds are formed by the overlapping of atomic orbitals. Sigma bonds are a result of the head-to-head overlapping of atomic orbitals whereas pi bonds are formed by the lateral overlap of two atomic orbitals

Answer 2

Answer:

pi bond:

• it is formed by direct(end to end) overlapping of orbitals
• sigma bonds are stronger than pi bonds

• single bond is always sigma bond
• sigma bond can exist independently

pi bond:

• formed by sideways or lateral overlapping of orbitals
• weaker tan sigma bond
• can't exist independently
• doesnot take part in hybridization
