RRC Group D Previous Paper 43 (Held On: 22 Oct 2018 Shift 2)

Answer 1

The correct answer is 5.

C₆H₁₄ is hexane. It has 5 structural isomers like n-hexane, 2-methyl pentane, 3-methyl pentane, 2,2-dimethyl butane, 2,3-dimethyl butane.

Important Points

Compounds with different physical properties were found to have the same elemental composition and molecular weight. Such compounds were called isomers.
The below table shows the number of constitutional isomers for each of the acyclic alkanes C_nH_2n+2, where n=1-10.
If the number of carbon atoms increases, the number of possible constitutional isomers increases rapidly.
