Explain the reason for the following observations.
00:06
Phenol does not react readily with pcl5 to form chlorobenging, but ethyl alcohol can react with the pcl5 easily.
00:16
Why? because we know that in the structure of phenol, lawn pair is present.
00:30
That's why this lawn pair is conjugate with the benzene ring.
00:33
And if this lawn pair is conjugate with the benzene ring, then what will happen? then at this bond, pi bond character will come.
00:45
If pi bond character will come then this bond will be strong and in oh cannot be easily broken.
00:53
That's why it will not react with the pcl5.
00:57
But in the c2h5 reaction, oh is not conjugate with any group.
01:06
That's why it can react easily pcl5 and we will get c2h5 cl...
