Alcohols

Question 1

What happens to solubility as the carbon chain increases?

Answer 1

Solubility decreases as the carbon chain length increases.

Question 2

How do you know if an alcohol is primary secondary or tertiary?

Answer 2

The number of carbon attached directly to the carbon atom bonded to the hydroxyl.

Question 3

What can primary alcohols get oxidised to?

Answer 3

Aldehydes or Carboxylic acids.

Question 4

What can secondary alcohols be oxidised to? by which method?

Answer 4

Heated under reflux to form
Ketones

Question 5

How do primary alcohols get oxidised to aldehydes?

Answer 5

Heated with oxidising agent
Under distillation

Question 6

How can a primary alcohol be oxidised to carboxylic acids?

Answer 6

Heated under reflex, with excess oxidising agent. it prevents the aldehyde forming, and full oxidation to a carboxylic acid can be formed.

Question 7

How are alcohols dehydrated and what do they form? What type of reaction is this?

Answer 7

Using Concentrated Phosphoric acid H3 PO4

it makes alkenes and water

Elimination

Question 8

What do alcohols with halide ions make?

Answer 8

Haloalkanes, in acidic conditions s H2SO4

Question 9

Condition for Oxidation reaction

Answer 9

Heat either reflux or distillation and Acidifies potassium dichromate

K2CR2O7/H+
