Question

Assertion and reason type question.
Assertion: Pi bond is never formed alone. It is
formed along with a sigma bond.
Reason: Pi bond is formed by sideway overlap of p-
orbitals only.​

Answer 1

Answer:

do you know one thing that this app is not for joke this is for student and like you make this app bad....

Explanation:

bcoz he dont want to meet alone

Answer 2

Answer:

• Assertion is true
• Reason is False

Explanation:

• Sigma bond - Sigma (σ) Bond is the strongest covalent bond. The head-on overlapping of the orbitals forms it.

• Pi bond - Pi (π) Bonds are also covalent bonds formed by sideways overlapping of p-p, p-d, and d-d orbitals. It is a weaker bond than the sigma bond.

• Since the bond energy of the sigma bond is greater than the pi bond.
• So we can say that sigma bonds are more stable bonds. Hence sigma bond forms before than pi bond.
• After the formation of sigma, pi bonds are formed.
• Hence, the pi bond is never formed alone. It is formed along with a sigma bond. The assertion is true.

• Pi bond can be formed by sideways overlapping of p-p, p-d, and d-d orbital. So, the Reason is false.
