First of all, before we talk about this question, we should talk about what is being by bond dissociation energy.
00:13
That is the measure of the strength of a chemical bond.
00:17
That means, if a bond is higher in energy, that needs higher energy to break that particular bond.
00:28
That means, it has higher dissociation energy.
00:31
So now let's talk about these examples.
00:36
First one has, all of them have halogens.
00:41
The first one is i'll draw only the halide and carbon bond.
00:46
First one has iodine in it and second one has bromine in it.
00:53
And third one has similarly chlorine atom.
00:58
And this chlorine, bromine, ivy, all are halogens.
01:03
And if you can remember the periodic table, when you go down the group, the atomic size is getting bigger and bigger...
