Answer:
The given molecules are:
CH2Br2
CH3NH2
LiF
C3H8
CF4.
Which compound consists of the hydrogen bond as the strongest intermolecular force.
Explanation:
The hydrogen bond is the electrostatic force of attraction that exists between the covalently bonded H-atom of one molecule and a high electronegative atom (N, O, F) of another molecule.
For example, H-bonding in water is represented below:
Among the given molecules,
CH2Br2 does not have H-bond because there is no either N or O or F atom in it.
In LiF also there is no H-atom and no hydrogen bond.
C3H8 also does not have H-bond in it.
CF4 also does not have H-atom or hydrogen bond in it.
The answer is CH3NH2(methylamine).
It has an intermolecular hydrogen bond in it as shown in the attachment.
The dashed line represents the H-bond.
