Current Question (ID: 10872)

Question:

$\text{The total number of isomers of } \text{C}_4\text{H}_8 \text{ are-}$

Options:

1. $8$
2. $7$
3. $6$ (Correct)
4. $5$

Solution:

$\text{Hint: Isomers are molecules of the same molecular formula but have a different arrangement of their atoms.}$ $\text{C}_4\text{H}_8 \text{ has 6 isomers. The name of the isomers are as follows:}$ $\text{(1) Cyclobutane}$ $\text{(2) 1-Methylcyclopropane}$ $\text{(3) 1-Butene}$ $\text{(4) cis-2-Butene}$ $\text{(5) trans-2-Butene}$ $\text{(6) 2-Methylpropene}$ $\text{The structures include cyclic compounds (cyclobutane and 1-methylcyclopropane) and alkenes (1-butene, cis-2-butene, trans-2-butene, and 2-methylpropene).}$
