Question

$C{H}_{3}C{H}_{2}C{H}_{2}C{H}_{2}N{O}_2$ and $C{H}_{3}CH\left(N{O}_2\right)C{H}_{2}C{H}_3$ is/are:

• A. chain isomers
• B. positional isomers
• C. functional isomers
• D. metamers

Answer 1

The correct option is B positional isomers

$C{H}_{3}C{H}_{2}C{H}_{2}C{H}_{2}N{O}_2$ and $C{H}_{3}CH\left(N{O}_2\right)C{H}_{2}C{H}_3$ are 1-nitro butane and 2-methyl 1-nitro propane and are positional isomers.
Compounds having same molecular formula and difference in the nature of carbon chain is called as chain isomers.
Hence, option $B$ is correct.
