MCQ
Assertion (A): Same number of electron pairs are present in resonance structures.
Reason (R): Resonance structures differ in the location of electrons around the constituent atoms.
  • ✓
    Both A and R are true and R is the correct explanation of A.
  • B
    Both A and R are true but R is not the correct explanation of A.
  • C
    A is true but R is false.
  • D
    A is false but R is true.
✓

Answer

Correct option: A.
Both A and R are true and R is the correct explanation of A.
(a) Both A and R are true and R is the correct explanation of A .
Explanation: In resonance the structures differ only in location of electrons around the constituent atoms, that is why these have same number of electron pairs, and also unpaired electrons are same.
