The question asked us to calculate the bond length of, so the bond length in ch2cl2 molecule.
00:18
So first we write to write the structure of this ch2cl is a tetrahedral molecule with 2cl and 2h.
00:34
So this is a tetrahedral, we have to find out bond length of two bonds.
00:39
One is ccl bond and the other one is ch bond.
00:43
To calculate this question has given certain data.
00:46
We have been provided with the covalent bond radii of few species.
00:58
The first one is for hydrogen it is 0 .28 angstrom.
01:08
Then for nitrogen they have given is 0 .70 angstrom.
01:19
Then for oxygen they have given is 0 .66 angstrom.
01:27
Then for cl they have given is 0 .99 angstrom.
01:36
So these are radii of atoms.
01:38
Then they have given for c double bond which is 0 .67 angstrom.
01:47
Then for c triple bond they have given which is 0 .61 angstrom.
01:54
Then for n triple bond they have given is 0 .55 angstrom...
