Question

Inductive effect involves:

• A. displacement of $\pi$-electrons
• B. delocalisation of $\pi$-electrons
• C. delocalisation of $\sigma$-electrons
• D. displacement of $\sigma$-electrons

Hint:

Inductive = $\sigma$ electrons; Resonance = $\pi$ electrons.

Answer 1

The Correct Option is D

Step 1: Concept
The inductive effect is a permanent effect involving $\sigma$-bonds.
Step 2: Analysis
It occurs due to the electronegativity difference between atoms, causing a partial shifting or displacement of $\sigma$-electron density along the chain.
Step 3: Conclusion
It specifically involves the displacement of $\sigma$-electrons.
Final Answer: (D)
