Question:medium

Which of the following effects is a permanent effect?

Show Hint

A simple memory trick:
• Inductive Effect \(\rightarrow\) Permanent
• Electromeric Effect \(\rightarrow\) Temporary (appears only when reagent attacks)
Updated On: Jun 18, 2026
  • Electromeric effect
  • Inductive effect
  • Both
  • None
Show Solution

The Correct Option is B

Solution and Explanation

Concept: Electronic effects in organic molecules include inductive (permanent σ-electron displacement), electromeric (temporary π-electron shift during reaction), resonance, and hyperconjugation.

Step 1: Distinguish permanent from temporary effects.

Inductive effect exists permanently in the ground state due to electronegativity differences. Electromeric effect occurs only in the presence of an attacking reagent and vanishes afterwards.

Step 2: Identify the permanent effect.

Only the inductive effect is permanent.

Final Answer:
Inductive Effect (option B).
