Concept Introduction:
A molecule is said to be chiral if it cannot be superimposed on its mirror image and if it does not possess an alternate axis of symmetry.
A carbon atom bonded in a tetrahedral structure to four different substituents in a molecule, it is called as a chiral centre or stereocentre.
If an organic molecule has more than one chiral carbon or chiral centre then the molecule may be achiral or chiral and it is depend upon whether the molecule has element of symmetry or not.
The elements of symmetry are-
- A plane of symmetry
- A centre of symmetry
- n-fold alternating axis of symmetry.
Answer to Problem 15.18P
Explanation of Solution
Since alkanes consist of only carbon and hydrogen, the lowest molecular weight alkane can have four different groups attached to it namely- hydrogen, methyl group, ethyl group, and propyl group.
So the molecule so formed is: 3-Methyl-Hexane.
3-Methyl-Hexane.

Answer to Problem 15.18P
Explanation of Solution
Since alkenes consist of only carbon and hydrogen, with a double bond, the lowest molecular weight alkene can have four different groups attached to it namely- hydrogen, methyl group, vinyl group, and ethyl group.
So the molecule so formed is: 3-Methyl-Pent-1-ene.
