Question

Which is not the characteristic of $\pi -$bond?

• A. $\pi$ bond is formed when a sigma bond already exists
• B. $\pi$ bonds are formed from hybrid orbitals
• C. $\pi$ bond may be formed by the overlapping of p orbitals
• D. $\pi$ bond results from lateral overlap of atomic orbitals

Answer 1

Answer: (B)

$\pi$ bonds are formed from hybrid orbitals

$\pi$ bond is formed between two atoms if a sigma bond already exists between them.
$\pi$ bonds are formed only by pure orbitals ($p-$orbitals), not from hybrid orbitals. They formed by lateral or sideways overlapping.
