Alcohols and phenols

Oxidation of a primary alcohol with acidified dichromate gives first:

• 1 An ester
• 2 An alkane
• 3 A ketone
• 4 An aldehyde

Oxidation of a secondary alcohol gives a:

• 1 Ketone
• 2 Alkane
• 3 Carboxylic acid
• 4 Aldehyde

Phenol is:

• 1 Strongly basic
• 2 Strongly acidic
• 3 Weakly acidic
• 4 Neutral

Ethanol and ethanoic acid react in the presence of an acid catalyst to form:

• 1 An ester
• 2 An ether
• 3 An aldehyde
• 4 An alkene

Methanol is poisonous because it is metabolised to:

• 1 Water only
• 2 Ethanol
• 3 Methanal and methanoic acid
• 4 Glucose

A tertiary alcohol is:

• 1 Resistant to oxidation by dichromate
• 2 Easily oxidised to an aldehyde
• 3 Easily oxidised to a ketone
• 4 Always a gas

The general formula of a saturated monohydric alcohol is:

• 1 CnH2n-1OH
• 2 CnH2n+1OH
• 3 CnHnOH
• 4 CnH2nOH

The reaction of phenol with bromine water gives a:

• 1 Blue solution
• 2 White precipitate
• 3 Green solid
• 4 Red gas
