Select correct statement?
1 Anti aromatic species have negligible tendency to form dimer.
2 Compounds having more no. of resonating structures are always more stable than compound having lesser no. of resonating structures.
3 The one which has higher resonance energy is always more stable than the other which has lower resonance energy.
4 - has lesser negative inductive effect as well as lesser mesomeric effect than -F group.

Statement A : Benzene exhibit two different bond lengths between carbon and carbon Statement B : Actual structure of benzene is a hybrid of following two structures.
1 Both Statements are incorrect.
2 Statement A is correct but Statement B is incorrect.
3 Statement A is incorrect but Statement B is correct.
4 Both statements are correct.
Explanation:
Benzene has a uniform bond distance of , a value intermediate between the single bond and double (134 pm) bonds. So, the option (2) is correct.

Assertion : Same number of electron pairs are present in resonating structures. Reason : Resonating structures differ in the location of electrons around the constituent atoms.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Resonating structures may have the same number of electrons but differ in electron arrangement. The reason is true, resonating structures differ in the distribution of electrons around the constituent atoms while maintaining the same overall number of electrons. So, the option (2) is correct.
