Yes, the dark stops the formation of a bromine radical
This is because chlorine is an electronegative group and is pulling electrons away from benzene. This makes the ring less reactive and more positive. Then when a positive electrophile tries to attach, the benzene does not want to react.
The substitution reactions of phenol are easier than benzene, phenol directly reacts with bromine and gives tribromo phenol while benzene requires FeCl3 as a catalyst and gives mono bromo phenol.
Chlorine
I believe its Calcium, because it is in group 2, and Bromine is not in group one or two, making Calcium more reactive.
due to extensive delocalization of pie-electrons of benzene , it do not undergoes Bayer's and bromine test. 6 carbon nuclei hold the pie electronic cloud which make it difficult for an electrophile to attack.
When Bromine is mixed with Benzene it becomes bromobenzene.
Bromine is way more reactive
Bromine, as a group 17 halogen, is extremely reactive
No!! Benzene wont de colourise bromine water although it is an unsaturated compound ,as it is an aromatic compound and it does not undergo addition reaction.
Benzene has a stable structure. Aspirin has an carboxylic group with delocalized electrons. So aspirin is more reactive than benzene.
Chlorine is more reactive
Bromine has more nuclear charge as compared to iodine. So, bromine easily attracts an electron and hence more reactive.
Meso-stilbene dibromide is an organic molecule. Its structure is a benzene ring bonded to a carbon with a hydrogen and a bromine. That carbon is bonded to another carbon with a bromine that is ANTI to the first bromine. This carbon is then also bonded to a benzene ring.
