a)ab)bc)cd)dCorrect answer is option 'C'. Can you explain this answer?

I have drawn only skeleton. It can be known that for C
5H
12 and C
6H
14, we have no isomerism. For C
7H
16 we have one isomer. So, the minimum carbon required for an alkane is C
7H
16.

The molecular formula for the alkane with the smallest molecular weight that possesses a stereogenic center is C7H16, which is option C.
Explanation:
- Alkanes are hydrocarbons that only contain carbon and hydrogen atoms. They have the general formula CnH2n+2, where n is the number of carbon atoms in the molecule.
- A stereogenic center, also known as a chiral center, is a carbon atom bonded to four different groups. It gives rise to stereoisomers, which are molecules that have the same connectivity of atoms but differ in their spatial arrangement.
- To determine the molecular formula for the alkane with the smallest molecular weight that possesses a stereogenic center, we need to consider the number of carbon atoms and the number of hydrogen atoms.
- Option A, C5H12, does not have enough carbon atoms to provide a stereogenic center.
- Option B, C6H14, also does not have enough carbon atoms to provide a stereogenic center.
- Option C, C7H16, has seven carbon atoms, which is enough to provide a stereogenic center. It is the correct answer.
- Option D, C8H18, has eight carbon atoms, which is also enough to provide a stereogenic center. However, it is not the smallest molecular weight alkane that possesses a stereogenic center.
Therefore, the correct answer is option C, C7H16, which is the alkane with the smallest molecular weight that possesses a stereogenic center.
