Let's discuss this question.
00:01
So here the question says that at room temperature, chlorine is a gas, bromine is a liquid and iodine is solid.
00:08
So we need to explain the intermolecular forces and the difference between these diatomic compounds.
00:14
Firstly, we can say intermolecular force of attraction, this forces of attraction between the neighboring molecule.
00:56
We can also say that intermolecular forces may be weak or strong depending on temperature and pressure.
01:42
So we can say if intermolecular force of attraction is very less than the molecules in gaseous form.
02:43
If more than molecules are in liquid form and if the force of attraction is very high, then molecules become.
03:33
So we can say that intermolecular force of attraction depends on the temperature and pressure.
03:42
Also, if the attraction is very less than the molecules are in gaseous form, if the attraction is more than molecules are in liquid forms and if attraction is very high then the molecules will be in the solid form.
03:57
Further, we can say that chlorine, that is, the l2, it is diatemic molecule formed by covalent bond and intermolecules.
04:42
Course of interaction is very low and molecule freely move and have melting point that is one zero minus one zero two degree celsius so here we can say therefore chlorine is gas at room temperature so here we can say there for chlorine is gas at room temperature so here we can say, firstly we all know that chlorine is a diatomic molecules and it is formed by the covalent bond and intermolecular forces of attraction.
06:04
So if the intermolecular forces of interaction is low, then the molecule will freely move and here the melting point of this molecule is given as minus 102 degrees celsius and therefore this chlorine is gase the room temperature.
06:19
Now let's see about bromine.
06:25
That is br2...
