Question

The functional isomer of $C{H}_{3}C{H}_{2}C{H}_{2}OH$:

• A. $C{H}_3-\underset{OH}{\underset{|}{C}H}-C{H}_3$
• B. $C{H}_{3}COC{H}_3$
• C. $C{H}_{3}OC{H}_3$
• D. $C{H}_{3}OC{H}_{2}C{H}_3$

Answer 1

The correct option is D $C{H}_{3}OC{H}_{2}C{H}_3$

$C{H}_{3}C{H}_{2}C{H}_{2}OH$

Mal formula: $C_3{H}_{8}O$

Funtional isomers are those unice than some mal formula but diff fuctional group.

A) $C{H}_3-\underset{ON}{\underset{|}{CH}}-C{H}_3$: mal-formula $=C_3{H}_{8}O$

B) $C{H}_{3}COC{H}_3$: mal formula $=C_3{H}_{6}O$

C) $C{H}_{3}OC{H}_3$: mal formula $=C_2{H}_{6}O$

D) $C{H}_{3}O{C}_2{H}_5$: mal formula $=C_3{H}_{8}O$

Options A and D have the same molecular formula $C_3{H}_{8}O$, but A has one same fuctional group $(-OH)$, while D has ether fuctional group.
