Front (Question)

How to identify an alcohol from the name?

Back (Answer)

Name ends in -ol

Front (Question)

How to identify an alcohol from the structure?

Back (Answer)

Contains the hydroxyl functional group (-OH)

Front (Question)

What is the general formula of alcohols?

Back (Answer)

CnH2n+1OH or CnH2n+2O

Front (Question)

Steps to name an alcohol

Back (Answer)

• Identify the longest carbon chain (methan‑, ethan‑, propan‑ etc). • Number the chain to give the –OH group the lowest possible number. • Add ‑ol to the end. Examples: propan‑2‑ol, pentan‑1‑ol.

Front (Question)

Chemical properties of alcohols.

Back (Answer)

Flammable

Front (Question)

Uses of alcohols

Back (Answer)

Used as fuels and solvents

Front (Question)

Solubility trend of alcohols

Back (Answer)

Methanol, ethanol and propanol are miscible with water; solubility decreases as size increases.

Front (Question)

Alcohol melting and boiling points trend

Back (Answer)

MP and BP increase with size due to stronger intermolecular forces.

Front (Question)

How to identify a carboxylic acid from the name?

Back (Answer)

Name ends in ‑oic acid.

#10

Front (Question)

How to identify a carboxylic acid from the structure?

Back (Answer)

Contains the carboxyl functional group (-COOH).

#11

Front (Question)

What is the general formula of carboxylic acids?

Back (Answer)

CnH2nO2

#12

Front (Question)

What functional group do carboxylic acids contain?

Back (Answer)

The carboxyl group (-COOH).

#13

Front (Question)

Steps to name a carboxylic acid:

Back (Answer)

• Identify the longest carbon chain. • The carboxyl group is always carbon 1, so no number is needed. • Add ‑oic acid. Examples methanoic acid and butanoic acid

#14

Front (Question)

Chemical properties of carboxylic acids:

Back (Answer)

pH less than 7 React with bases and metals

#15

Front (Question)

Uses of carboxylic acids

Back (Answer)

Used in preservatives, soaps, medicines.

#16

Front (Question)

Uses of vinegar (ethanoic acid)

Back (Answer)

Used in cleaning and food preservation.

#17

Front (Question)

Solubility trend of carboxylic acids

Back (Answer)

Methanoic–butanoic acids are miscible with water; solubility decreases as size increases.

#18

Front (Question)

Carboxylic acid melting and boiling points trend

Back (Answer)

MP and BP increase with size due to stronger intermolecular forces.

#19

Front (Question)

Why does ethanoic acid have a higher MP/BP than ethane, ethene, or ethanol?

Back (Answer)

Ethanoic acid molecules are held together more strongly by intermolecular forces, requiring more energy to separate.

#20

Front (Question)

Why is methane a gas at room temperature?

Back (Answer)

Methane has weak intermolecular forces, so little energy is needed to separate the molecules.

#21

Front (Question)

Identify the alcohol and carboxylic acid from the names: 1. Octanoic acid 2. Heptan-2-ol

Back (Answer)

Octanoic acid → Carboxylic acid Heptan-2-ol → Alcohol

#22

Front (Question)

Identify the alcohol and carboxylic acid from the formulae: • CH3CH2CH(OH)CH3 • CH3CH2-COOCH3 • CH3CH2-COOH

Back (Answer)

• butan-2-ol → alcohol • propanoic acid → carboxylic acid

#23

Front (Question)

What is the systematic name of this molecule?

Back (Answer)

Pentan-3-ol

#24

Front (Question)

What is the systematic name of this molecule?

Back (Answer)

Butanoic acid
