When halogens reacts with cold NaOH , it leads to the formation of :
Sodium hypohalite
Sodium halate
Both 1 & 2
none of these
As we learnt ,
Reaction of NaOH with halogens -
1. With cold and dilute NaOH, hypohalite (NaOX) is formed
2. With hot and concentrated NaOH, halate(NaXO3) is formed
The reactions are given as:
Where X= Cl, Br or I
Therefore, option(1) is correct.
