(a)
Interpretation:
Structural formula for the given compounds has to be drawn.
Concept Introduction:
Nomenclature of organic compounds:
The naming of the organic compound is given by IUPAC (International Union for pure and applied chemistry). In the IUPAC names consist of certain rules for giving chemical names they are,
- The longer number of Carbon chain of a compound is identified this is called parent of the compound.
In the cyclic compounds the number of carbon involving in ring formation is called parent of the compound.
- The compound have more than one parent chains means the larger number of substitutions present in the chain is consider as a parent chain.
- The names of all substituents are arranged by alphabets to starts with lowest numbering.
- In the complex substituent having compounds the substituent name is assigned by a name each of them based on numbers going away from the parent.

Nomenclature of organic compounds:
The naming of the organic compound is given by IUPAC (International Union for pure and applied chemistry). In the IUPAC names consist of certain rules for giving chemical names they are,
- The longer number of Carbon chain of a compound is identified this is called parent of the compound. For
alkenes , suffix will be ‘ene’. - The compound have more than one parent chains means the larger number of substitutions present in the chain is consider as a parent chain.
- The names of all substituents are arranged by alphabets to starts with lowest numbering.
- In the complex substituent having compounds the substituent name is assigned by a name each of them based on numbers going away from the parent.
R and S nomenclature:
It is used to assign the molecule using CIP rules.
The CIP rules are as follows:
- Select the chiral carbon and assign the numbers according to the decreasing
atomic mass of atoms attached to it. - If the numbering follows clockwise direction then the atom is termed as R and if it follows anti-clockwise direction then atom is termed as S.
(c)

Substituents are arranged symmetrically and the stereo centers are opposite. Thus, the prefix meso is given.

In a cis isomer, groups are attached on the same side of the ring.
In a trans isomer, groups are attached on the opposite side of the ring.
