Statement -1: Phenol is more reactive than benzene towards electrophil...
Option a is correct as in phenol the negative charge increases in the benzene ring due to -M effect thus making it more comfortable for electrophillic substitution than benzene ring.
statement 1 says the same thing as i said above and statement 2 is also correct because the carbocation phenoxide ion is more stable than carbocation of benzene ring.

Statement -1: Phenol is more reactive than benzene towards electrophil...
Statement -1: Phenol is more reactive than benzene towards electrophilic substitution reactions.

Statement -2: In the case of phenol, the intermediate carbocation is more resonance stabilized.

Explanation:
To determine the correct option, let's evaluate both statements one by one.

Statement -1: Phenol is more reactive than benzene towards electrophilic substitution reactions.
Electrophilic substitution reactions involve the replacement of an atom or a group of atoms in a molecule by an electrophile. In benzene, the electron density is evenly distributed due to the delocalization of π electrons in the aromatic ring. However, in phenol, the -OH group attached to the benzene ring donates electron density through resonance, making the ring more electron-rich. This increases the reactivity of phenol towards electrophilic substitution reactions compared to benzene. Hence, Statement -1 is correct.

Statement -2: In the case of phenol, the intermediate carbocation is more resonance stabilized.
The intermediate carbocation formed during electrophilic substitution reactions is stabilized by resonance when there are multiple resonance structures that can delocalize the positive charge. In the case of phenol, the lone pair of electrons on the oxygen atom can delocalize the positive charge through resonance, resulting in resonance-stabilized intermediate carbocations. This resonance stabilization provides additional stability to the intermediate, making the reaction more favorable. Hence, Statement -2 is correct.

Conclusion:
Both Statement -1 and Statement -2 are correct. Additionally, Statement -2 is the correct explanation of Statement -1. The electron-donating nature of the -OH group in phenol enhances its reactivity towards electrophilic substitution reactions, and the resonance stabilization of the intermediate carbocation further increases the reactivity. Therefore, the correct option is 'A' - If both Statement -1 and Statement -2 are correct, and Statement -2 is the correct explanation of the Statement -1.

On the basis of aromaticity, there are three types of compounds i.e. aromatic, non-aromatic and antiaromatic. The increasing order of stability of these compounds are is under: Anti-aromatic compound < non-aromatic compound < aromatic compounds. Compounds to be aromaticfollow the following conditions (according to valence bond theory)(i) The compounds must be be cyclic in structure having (4n + 2)π e–, where n = Hückel’s number = 0, 1, 2, 3 et.c(ii) The each atoms of the cyclic structure must have unhybridised p-orbital i.e. the atoms of the compounds have unhybridised p-orbital i.e. usually have sp2 hybrid or planar.(iii) There must be a ring current of π electrons in the ring or cyclic structure i.e. cyclic structure mustundergo resonance .Compounds to be anti-aromatic, it must have 4nπe– where n = 1, 2… and it must be planar and undergo resonance. Non-aromatic compounds the name itself spells that compounds must be non-planarirrespective of number of π electrons. Either it has 4nπe– or (4n + 2) π electrons it does not matter.The rate of reaction of any aromatic compounds depends upon the following factors:(i) Electron density(ii) stability of carbocation producedHigher the amount of electron density of the ring, higher will be its rate towards aromatic electrophilic substitution and vice-versa. Similarly, higher will be the stability of the produced carbocation after the attack of electrophile, higher will be its rate towards aromatic electrophilic substitution. There is a great effect of kinetic labelling on the rate of aromatic electrophilic substitution. As we known that higher the atomic weight or, molecualr weight, higher will be the van der Waal’s force of attraction or, bond energy. Since there will be effect of kienetic labelling if the 2nd step of the reaction will be the slow step, (r.d.s.) otherwise there will be no effect of kinetic labelling.Q. Which of the following is correct order of the rate of reaction of C6H6, C6D6 and C6T6 towardssulphonation?
