How p-niro toluene can be converted to benzene?

(A): The first ionisation energy of B is less than that of Be (R) : The penetration ability of s- electrons is higher than that of p- electrons The correct answer is

Why toluene is more reactive than benzene towards electrophilic substitution reactions?

Why toluene is more reactive than benzene towards electrophilic substitution reactions?

Benzene and toluene form an ideal solution over the entire range of composition. The vapour pressure of pure benzene and toluene at T(K) are 50mm Hg and 40 mm Hg respectively. What is the mole fraction of toluene in vapour phase when 117 g of benzene is mixed with 46g of toluene? (molar mass of benzene and toluene are 78 and 92 g mol^(-1) respectively).

At 70^@C vapour pressure of pure benezene and pure toluene are 500 torr and 200 torr, respectively. In a homogeneous mixture of toluene with benzene at 70^@C , the mole fraction of benezene is 0.4. Calculate the vapour pressure of the mixture.

(A): Aniline is a weak Lewis base than benzylamine. (R): In aniline, there is mesomeric effect between benzene ring and amino group.

The nitro group is a very strong deactivating group Nitro benzene undergoes nitration at a rate only 10-4 times that of benzene. The nitro group is a meta-directing group. When nitrobenzene is nitrated with nitration mixture 93% of meta substituted product is formed. Ring deactivating groups are :
