Hello, in this given problem, which of the following molecules are polar? so the given molecules are when xf4, bf3, h2o and ch2, cl2.
00:42
For the first compound, xf4.
00:48
Structure of xf4 is xe f4, sorry, xef4, xef4, xef4, xef4, xef4, xef4, xef4.
01:04
So, the dipole moment is in opposite direction.
01:26
All will cancel out each other.
01:30
There are two long pair on axi.
01:39
This is non -polar.
01:42
Symmetrical molecules, molecules, electronegative difference over all, electro -negativity difference, cancel out.
02:36
So this is.
02:39
Non -polar.
02:46
This is the answer for xefo.
02:51
Now for bf3.
02:59
So the structure of bf3 is bf3.
03:14
Direction of dipole moment is upper side of this f, lower side of both of these f...
