So, the question is among hydrogen, methane and ammonia which will form hydrogen bond when they were in the liquid state or liquid phase.
00:17
So, as you can see hydrogen is a non -polar molecule and the hydrogen is a very electropositive and the electronegativity of hydrogen is very less.
00:37
Electronegativity is less, okay.
00:45
So, and in molecular state, so there is no difference in electronegativity between the hydrogen.
00:53
So, there is no chance of hydrogen bonding.
00:56
Whereas in the case of methane, methane will form a structure like this tetrahedral structure.
01:04
So, there is no bond pair of electron with carbon and as well as the electronegativity difference between carbon and hydrogen is very less.
01:25
Electronegativity difference is less.
01:29
So, carbon do not have a tendency to attract electron towards itself of the hydrogen to make hydrogen electron deficient...
