Front (Question)

Do alcohols or carboxylic acids of similar sizes have a higher boiling point

Back (Answer)

Carboxylic acids

Front (Question)

Why do carboxylic acids have a higher boiling point than alcohols of similar size

Back (Answer)

Because they can both form hydrogen bonds but carboxylic acids also has a permanant dipole

Front (Question)

Why does the boiling point of carboxylic acids increase when the size of the carboxylic acid increases

Back (Answer)

Since there are more electrons and a larger surface area so an increase points of contact so there are more London forces

Front (Question)

When naming carboxylic acids, what carbon is carbon one

Back (Answer)

The carbon bonded to the carboxylic acid group

Front (Question)

When reacting a phenol with a carboxylic acid attached, and you add sodium hydroxide / a strong base, what is the product

Back (Answer)

Where the Na+ is attached to the O- of the OH and the O- of the COOH and H2O is produced

Front (Question)

Is the OH acid or carboxylic acid a stronger acid

Back (Answer)

Carboxylic acid

Front (Question)

When adding sodium carbonate/ weak base to a phenol with carboxylic acid attached what is the product

Back (Answer)

Where Na+ is attached to the COOH but NOT the OH

Front (Question)

Why does sodium carbonate only react with the carboxylic acid and not the OH group when added to a phenol with a carboxylic acid

Back (Answer)

Because COOH is a stronger acid than the OH

Front (Question)

What is the name of the CH3COO- ion

Back (Answer)

Ethanoate

#10

Front (Question)

What are the products: Ethanoic acid + NaOH

Back (Answer)

CH3COONa + H2O - Sodium ethanoate + water

#11

Front (Question)

What are the products: CH3COOH + metal e.g. Na

Back (Answer)

NaCH3COO + H2 Sodium ethanoate + hydrogen gas

#12

Front (Question)

What are the products: CH3COOH + NA2CO3

Back (Answer)

NaCH3COO + CO2 + H2O Sodium ethanoate + carbon dioxide + water

#13

Front (Question)

What are the products: CH3COOH + metal oxide (NaO)

Back (Answer)

NaCH3COO + H2O Sodium ethanoate + water

#14

Front (Question)

What are the products: CH3COOH + NH3

Back (Answer)

NH4CH3COO

#15

Front (Question)

What are the names of the 4 derivatives of carboxylic acids

Back (Answer)

• Esters • Acyl chloride • Acid anhydride • Amide

#16

Front (Question)

How to name esters

Back (Answer)

Draw a line between the COO- ion and the methyl group

#17

Front (Question)

When naming esters, what name comes first the ethanoate or the methyl

Back (Answer)

Methylethanoate

#18

Front (Question)

What are the products: Alcohol + carboxylic acid

Back (Answer)

Ester + water

#19

Front (Question)

What are the conditions for the reaction between carboxylic acid and alcohol forming an ester

Back (Answer)

• Concentrated sulfuric acid • Heat

#20

Front (Question)

What is the equation for the base hydrolysis of an ester

Back (Answer)

Ester + hydroxide -> Carboxylate ion + alcohol

#21

Front (Question)

What does ester and water make with an acid catalyst

Back (Answer)

Carboxylic acid + alcohol

#22

Front (Question)

Is the acid hydrolysis or base hydrolysis of an ester reversible

Back (Answer)

The acid hydrolysis is reversible

#23

Front (Question)

Why is the acid hydrolysis of ester a revesible reaction

Back (Answer)

Because the acid hydrolysis is in the presence of an acid catalyst and the products of the acid hydrolysis is carboxylic acid and alcohol

#24

Front (Question)

Why does the base hydrolysis of an ester produce a higher yield than the acid hydrolysis of esters

Back (Answer)

Because the base hydrolysis is not reversible whereas the acid hydrolysis is reversible
