#1
Front (Question)

Nucleophilic addition reactions of ethanoic acid with NaBH4

Back (Answer)

See page 458

#2
Front (Question)

Nucleophilic addition of carbonyl compounds with HCN/ H+(aq)

Back (Answer)

Page 458

#3
Front (Question)

How so you show the weak acidity of phenols

Back (Answer)

• does neutralise NaOH - doesn’t neutralise carbonates

#4
Front (Question)

Why is phenol classed as a weak acid?

Back (Answer)

• phenol partially dissociates producing phenoxide ion and a proton

#5
Front (Question)

Identify a carbonyl compound from the melting point of the derivative

Back (Answer)

• add 2,4- DNP • yellow precipitate • recrystallise the precipitate and measure the melting point • compare the melting point with the known compounds

#6
Front (Question)

Water solubility of carboxylic acids in terms of hydrogen bonding

Back (Answer)

• C=O and O-H are both polar • both form hydrogen bonds • larger the carbon chain, decreasing solubility after 4 carbons

#7
Front (Question)

Describe how you would obtain a pure dry sample of alkene from the reaction mixture

Back (Answer)

• use separating funnel to separate organic layer and aqueous layer • drying with anhydrous salt • redistillation

#8
Front (Question)

Draw the formation of acyl chlorides from carboxylic acids

Back (Answer)

• use SOCl2 - page 466

#9

Front (Question)

Why do amines act as base

Back (Answer)

-lone pair of electrons on the nitrogen can accept a proton
