Question

Which among the following is incorrect statement?

Options
  1. a

    Electromeric effect dominates over inductive effect

  2. b

    The electromeric effect is temporary effect

  3. c

    The organic compound shows electromeric effect in the presence of the reagent only

  4. d

    H⁺ shows negative electromeric effect

Correct Answerd

H⁺ shows negative electromeric effect

Detailed Solution

Step 1: Analyzing the Electromeric Effect The electromeric effect is temporary and occurs in the presence of a reagent.

  • +E effect: Electrons move toward the reagent (occurs with electrophiles like \ceH+\ce{H+}).
  • -E effect: Electrons move away from the reagent (occurs with nucleophiles like \ceCN\ce{CN-}).

Step 2: Finding the Incorrect Statement \ceH+\ce{H+} is an electrophile, so it induces a positive (+E) effect. Saying it shows a negative effect is incorrect.
