Question

Inductive effects involves :

• A. displacement of $\sigma$electrons resulting in polarisation
• B. displacement of $\pi$ electrons resulting in polarisation
• C. delocalisation of $\sigma$ electrons
• D. delocalisation of $\pi$ electrons

Answer 1

Answer: (A)

displacement of $\sigma$electrons resulting in polarisation

Inductive effect is polarisation of a $\sigma$ bond due to electron withdrawing or electron donating effect of adjacent groups or atoms.
