C3 = Alcohols, Carboxylic Acid And Esters

Question 1

Uses of alcohols, carboxylics and esters

Disadvantages

Answer 1

Fuel, drinking, solvents

D: Alcohol can lead to death, to produce ethanol biofuel a lot of land used

Question 2

What is produced when ethanol (alcohol) is oxidised?

Answer 2

Carboxylic

Ethanoic acid

Question 3

What happens to alcohols in the air and how is this useful

Answer 3

Co2 and H20 formed

Used for fuel

Question 4

What happens when alcohol reacts with sodium

Answer 4

Hydrogen gas

Question 5

When acids are added to carbonates what is created

Answer 5

Salt

Co2 + H20 (carbon dioxide makes it fizz)

Question 6

What are the homologous series of alcohols, carboxylics and esters?

Answer 6

Alcohol = OH

Carboxylic = COOH

Ester = COO

Question 7

What are the endings for alcs, carbs and esters

What are the starts for the first 4 terms

Answer 7

Al = anol

Car = anoic

Est = noate

Starts : (In order)

Meth-
Eth- (only one we can consume)
Prop-
But-

Question 8

Why are Carboxylic acids weak?

Answer 8

Due to being a reversible reaction only some of the acidic H+ ions disassociate

Question 9

Complete:

Carboxylic acid + alcohol =

Answer 9

Ester (and water)

Ethanoic acid + ethanol = ethylethanoate + H20
