Question

Hyperconjugation involves overlap of the following orbitals:

• A. $\sigma -\sigma$
• B. $\sigma -p$
• C. $p-p$
• D. $\pi -\pi$

Answer 1

The correct option is B $\sigma -p$

Hyper conjugation involves overlap of p orbitals. It is the interaction of the electrons in a sigma bond (usually CH or CC) with an adjacent empty (or partially filled) non-bonding p-orbital, anti bonding or orbital, or filled orbital, to give an extended molecular orbital that increases the stability of the system.
