Alcohols

Question 1

B.P?

Answer 1

The alcohols have relatively low volatility and
high boiling points due to their ability to form
hydrogen bond between alcohol molecules.

Question 2

Primary alcohols [0] to

Answer 2

Aldehyde ——> Carboxylic acid
reagents (both): acidified potassium dichromoate and dilute S04

Aldehyde - distil
Carboxylic acid - heat under reflux

Question 3

Secondary alcohols [0] to

Answer 3

Ketones
reagents: dilute S04 and acidifed potassium dichromate
conditions : heat under reflux

Eq:
alcohol + [0] —–> Ketone + H20

Question 4

Tertiary alcohols [0] to

Answer 4

This cannot be further [0] using dilute S04 and acidified potassium dichromate, only combustion.
This is because the Hydrogen atom is not bonded to the Carbon with the -OH
