Identify the correct order of boiling points of the following compounds: `underset(1)(CH_(3)CH_(2)CH_(2)CH_(2)OH)`, `underset(2)(CH_(3)CH_(2)CH_(2)CHO)`
`underset(3)(CH_(3)CH_(2)CH_(2)COOH)`

A

`1 gt 2 gt 3`

B

` 3 gt 1 gt 2`

C

`1 gt 3 gt 2 `

D

` 3 gt 2 gt 1 `

Text Solution

Verified by Experts

The correct Answer is:
B
`-COOH` and `COCH_(3)` are meta directing group due to the presence of `-overset(O)overset(||)(C)-`,similarly -CN is also meta directing due to the presence of multiple bond while `NHCOCH_(3)` is ortho`//` para directing group decrease of less electron density over `- overset(O)overset(||)(C)-` group.
