Question

1-nitro butane and 2-methyl 1-nitro propane are :

• A. Chain isomers
• B. positional isomers
• C. Functional isomers
• D. metamers

Answer 1

The correct option is A Chain isomers

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