The question given is draw the lewis structure for the following compounds and make certain show all calculations for building up and using the valise electron pool.
00:08
All items have the correct formal charge and all.
00:11
So we would start with cs2.
00:15
So first would be cs2.
00:19
Over here, lewis would be f.
00:26
So over here, formal charge for this is equal to 0 and for formal charge for 50 is equal to again, so, vepa type, vesper type is linear for this and electronic molecular configuration is also linear.
00:48
Electronic molecular configuration is also linear for this.
01:00
Bond angle is 180 degree.
01:07
Next thing is, it is non -polar due to symmetry.
01:13
Now for the second part we have bf3 so the structure would be fluorine fluorine so formal charge on b would be 3 minus 6 by 2 divided by 2 which is 0 formal charge on f would be 7 minus 6 minus 2 divided by 2 which is 0 vsper geometry vsper type would be trigonal we have three bond pair and no loan pair over here.
01:52
And next thing is, electronic and molecular configuration is triangular, trigonal, trigonal electronic and molecular configuration and bond angle is, bond angle is 120 degree, and it is non -polar molecule due to its symmetric geometry...
