Interpretation:The structural formulas for the given molecules need to be drawn. The mirror images of each molecule need to be drawn.
Concept Introduction:Chemical bonds are represented by single, double or triple bonds. When carbon is bonded with different atoms, this carbon is known as a chiral carbon.

Answer to Problem 7E
Carbon with different atoms is referred to as an asymmetrical carbon. If mirror image of one asymmetrical carbon compound is not super imposable over its compound, then it’s an optical active isomer.
Explanation of Solution
Enantiomers are chiral molecules which aremirror images of each other. The molecules are non-superimposable on one another.
The structural formulas and mirror images of CH4, CFH3, CClFH2 and CBrClFH are as follows:
Here, asymmetric compound have non-superimposable mirror images.
