Question

n-pentane and iso-pentane are ___ isomers

• A. Chain
• B. Position
• C. Geometrical
• D. Optical

Answer 1

The correct option is A Chain

$H_3\underset{1}{C}-\stackrel{C{H}_3}{\stackrel{|}{\underset{2}{CH}}}-\underset{3}{C{H}_2}-\underset{4}{C{H}_3}$

$\underset{1}{C{H}_3}-\stackrel{C{H}_3}{\stackrel{|}{\underset{C{H}_3}{\underset{2|}{C}}}}-\underset{3}{C{H}_3}$

Both isomers have different carbon chain
