1
Q
what is the difference in reactivty in benzen and alkene
A
electron density is higher in alkene and is loclated in carbon double bond where electron density is higher in benzen and delocalsied in ring ,
alkene has a higher reactivty and polarises bromine whereas reactivty in benzene is lower , and unable to polarise bromine
2
Q

A
conc h2s04
3
Q
what is strcturul fromaul of phenol
A
c6h5OH
4
Q
what is 1 test for phenol
A
add bromine , a white precipitate is formed
5
Q
what is the 2nd test for phenol
A
add indictor to show acidty , add sodium carbonate , no fizzing
6
