yeh stability wale order ko explain karo pls!!
Answers
As they said, E forms EX3, EX4 and EX6.
Let me tell you using an example here.
Take OX2. where O is Oxygen and X is halogen.
Which is stable, OF2 or OCl2 or OBr2 ? so according to the order of stability they've given, OF2 is the most stable.
OI2 where I is iodine may easily dissociate into O2- and I- ions.
clear? if not just tell me in one of my questions, I will explain more
Answer:-it is asking that which halogen's compound will be more stable.
The molecules will be more stable if the elements present in it do not break easily
As we know that flourune is the most elecronegative element,due to it's small size,so it will attract the other elements of the molecule more strongly ,so it will not break easily...
Simlilarly chlorine is more elecronegative than bromine and iodine ,so it hold the other elements of molecules so tightly so that they did not break...so they will be more stable than compounds of bromine and iodine....
For example:-OF2 will be more stable than OI2, because atoms of flourine atom will hold the oxygen more strongly than that of iodine
