Question 4

Phenol

Answer 4

A benzene ring where one of the hydrogen atoms has been substituted for a hydroxyl group.

Question 5

Primary alcohol

Answer 5

An alcohol in which the -OH is attached to a primary carbon atom (i.e. RCH2OH). Primary alcohols can be oxidised with Cr2O72-/H+ to form either an aldehyde or a carboxylic acid, depending on the conditions.

Question 6

Secondary alcohol

Answer 6

An alcohol in which the -OH is attached to a secondary carbon atom (i.e. R2CHOH). Secondary alcohols can be oxidised under reflux with Cr2072-/H+ to form a ketone.

Question 7

Tertiary alcohol

Answer 7

An alcohol in which the -OH is attached to a tertiary carbon atom (i.e. R3COH)
