Question

Which of the following is a permanent electron displacement effect?

• A. Electromeric
• B. Inductive
• C. Inductomeric
• D. All of the above

Answer 1

The correct option is B Inductive

• Inductive effect is the permanent electron displacement effect because always in covalent bond electron density more toward that atom who has higher electronegativity.
• Inductomeric effect is the temporary effect which enhances the inductive effect and it accounts only in the presence of an attacking reagent. Example, In methyl chloride the - I effect of. group is further increased temporarily by the approach of hydroxyl ion.
• Electromeric effect is a temporary effect and observed only in organic compounds with multiple bonds in the presence of an attacking reagent
