(a)
Interpretation:
The structures of the four given molecules must be drawn indicating whether those are polar or non polar.
Concept Introduction:
Lewis structure is the representation of molecules showing the electron dots present in each atom.
A polar molecule has non zero bond moments whereas a non polar molecule has zero bond moments.
(b)
Interpretation:
Which two molecules are liquid and which two are gases as room temperature must be predicted along with proper explanation.
Concept Introduction:
For liquids intermolecular forces are stronger as compared to gases.
(c)
Interpretation:
The given compounds must be ranked from lowest to highest boiling point with proper justification.
Concept Introduction:
Molecules having stronger intermolecular forces show higher boiling points.
