Which one of the following is not true regarding electromeric effect?
Options
- AIt is a temporary effect
- BIt operates on multiple bonds
- CIt requires an attacking reagent
- DIt results in the appearance of partial charges on the carbon atoms
Correct answer
D. It results in the appearance of partial charges on the carbon atoms
Step-by-step solution
In electromeric effect, there is complete transfer of -electrons from one atom to other to produce temporary polarity on atoms joined by multiple bonds. Therefore, there is no required partial charge on substrate (i.e., C-atoms).
