Question

Inductive effect involves ________.

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

Hint:

Inductive effect involves ____.

Answer 1

The Correct Option is B

Step 1: Concept
The inductive effect is a permanent effect where a substituent group causes the polarization of a molecule through $\sigma$-bonds.
Step 2: Analysis
Unlike resonance or electromeric effects, the inductive effect does not involve the movement of $\pi$-electrons or the complete delocalisation of electrons.
Step 3: Conclusion
It involves only the partial displacement of $\sigma$-electrons toward the more electronegative atom in a chain.
Final Answer: (B)
