Halogenation Flashcards
1
Q
During Halogenation which medium should be proffered
A
Acidic or basic
2
Q
Alpha beta unsaturated carbonyl compound + br2
Benzene + Br2
Benzene +Br2 + ALCL3
A
No
No
Generate Br+ it is possible
3
Q
How can a carboxylic acid can be halogenation
A
By converting it in to acyl chloride
4
Q
In carbonyl compound which center is soft
A
Alpa carbon
5
Q
Soft nucleophile
Hard nucleophile
A
Soft : pph3/net3, Rsh [ GIVE SN2] AT ALPHA CARBON
Hard : ROH, H2O,NH3 [ GIVE NS ]AT CARBONY CARBON
6
Q
Why basic halogenation no occur because alpha carbon of carbonyl compound undergoes
A
Halo form chbr3
7
Q
C=o,c—oh,c—lg

Give iodoform test
8
