Key Concept Flip

What type of compound is indicated by a chemical name ending in '-ane'?

Answer Flip

The '-ane' suffix indicates the compound is an alkane. Alkanes are saturated hydrocarbons containing only single bonds between carbon atoms.

Example: methane (CH₄).
Key Concept Flip

What type of compound is indicated by a chemical name ending in '-ene'?

Answer Flip

The '-ene' suffix indicates the compound is an alkene. Alkenes are unsaturated hydrocarbons containing at least one carbon-carbon double bond.

Example: ethene (C₂H₄).
Key Concept Flip

What type of compound is indicated by a chemical name ending in '-ol'?

Answer Flip

The '-ol' suffix indicates the compound is an alcohol. Alcohols contain a hydroxyl (-OH) group bonded to a carbon atom.

Example: ethanol (C₂H₅OH).
Key Concept Flip

What type of compound is indicated by a chemical name ending in '-oic acid'?

Answer Flip

The '-oic acid' suffix indicates the compound is a carboxylic acid. Carboxylic acids contain a carboxyl (-COOH) group.

Example: ethanoic acid (CH₃COOH).
Key Concept Flip

Give the formula for But-1-ene.

Answer Flip

The formula for But-1-ene is C₄H₈. It is an alkene with a double bond between the first and second carbon atoms in the chain.

Key Concept Flip

Give the formula for But-2-ene.

Answer Flip

The formula for But-2-ene is C₄H₈. It is an alkene with a double bond between the second and third carbon atoms in the chain.

Key Concept Flip

Give the formula for propan-1-ol.

Answer Flip

The formula for propan-1-ol is C₃H₈O. It is an alcohol with the -OH group attached to the first carbon.

Key Concept Flip

Give the formula for propan-2-ol.

Answer Flip

The formula for propan-2-ol is C₃H₈O. It is an alcohol with the -OH group attached to the second carbon.

Key Concept Flip

Give the formula for butan-1-ol.

Answer Flip

The formula for butan-1-ol is C₄H₁₀O. It is an alcohol with the -OH group attached to the first carbon.

Key Concept Flip

Give the formula for butan-2-ol.

Answer Flip

The formula for butan-2-ol is C₄H₁₀O. It is an alcohol with the -OH group attached to the second carbon.

Key Concept Flip

What two products are formed in complete combustion of alkanes?

Answer Flip

Complete combustion of alkanes produces carbon dioxide and water (CO₂ + H₂O). This occurs when there's a sufficient supply of oxygen.

Key Concept Flip

What conditions are required for halogenation of alkanes?

Answer Flip

Halogenation of alkanes requires photochemical conditions, specifically ultraviolet (UV) light. This energy is needed to break the bond in the halogen molecule (

Example: chlorine) and initiate the reaction by forming free radicals.
Key Concept Flip

Name the product of the reaction between propanoic acid and sodium hydroxide.

Answer Flip

The product is Sodium propanoate. This is a neutralisation reaction, where a carboxylic acid reacts with a base to form a salt and water.
