With hydrogen in a catalized reaction
Nitrobenzene has a nitro group.Benzene lacks that group
dintro benzene is reduced in presence of Na2S2
aniline
because nitro group is ring deactivating group, nitration of nitro benzene is more difficult than benzene.
1. benzene to nitro benzene through nitration 2. nitro benzene to m-bromonitrobenzene by bromination 3. m-bromonitrobenzene to m-bromoaniline through halogenation in presence of Sn+HCl.
Pale yellow
benzyl amine is the most basic
yes because amine forming salt with acid and it will be meta active
Partially true because benzene also obtained from other sources.
It s the structure and bonding of Aniline, Phenol, Benzene and Toluene that causes the differences in the boiling points.
preparation of m-nitro benzoic acid from benzene
The lone pair on the nitrogen of aniline is delocalised into the pi-system of the benzene ring and is therefore less available for attack on a proton.
