Answer:
The correct answer is option B, that is, C5H12.
Explanation:
The two isomeric forms of pentane are iso-pentane and n-pentane. The isomeric form of n-pentane is iso-pentane. The isomers exhibit similar molecular formula, however, differ in the atomic arrangement projected in the three-dimensional and the alignment of atoms mainly leading to the formation of a distinct set of characteristics. In this situation, iso-pentane also exhibits a molecular formula of an alkane C5H12.
