Q18 / 200 · AP EAMCET 2001 · Chemistry

Which one of the following pairs of compounds are functional isomers?

  • A
    $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{OH},\left(\mathrm{CH}_3\right)_2 \mathrm{CHCH}_2 \mathrm{OH}$
  • B
    $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{OH},\left(\mathrm{CH}_3\right)_2 \mathrm{CHCH}_2 \mathrm{OH}$
  • C
    $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{OH}, \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{Cl}$
  • Correct answer
    D
    $\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{OH}, \mathrm{CH}_3-\mathrm{O}-\mathrm{CH}_2 \mathrm{CH}_3$

Solution

In option (d) there are two different functional groups i.e., $-\mathrm{OH}$ and $-\mathrm{O}-$. So, these are functional isomers.

Hence, the correct answer is option: 'D'.
