Organic alkanes

Alkane to halogenoalkane

• excess oxygen and heat

• halogen at room temperature

• halogen and UV light

• hydrogen halide at room temperature

Alkane to carbon dioxide and water

• excess oxygen and heat

• limited oxygen and heat

• halogen and UV light

• water, warm mixture

alkane to carbon monoxide (and/or carbon) and water

• halogen and UV light

• excess oxygen and heat

• limited oxygen and heat

• water, warm mixture

The products of incomplete combustion of a hydrocarbon are

• carbon dioxide and water

• water only

• carbon monoxide

• carbon monoxide and water

The type of mechanism for alkanes reacting with a halogen is

• electrophilic addition

• electrophilic substitution

• elimination

• free radical substitution

A series of compounds with the same functional group is called

• homologous series

• structural isomers

• alkanes

• functional group

Alkanes are

• unsaturated hydrocarbons

• saturated hydrocarbons

• polymers

• monomers

Which statement is correct about thermal cracking?

• A pressure between 100 and 200kPa is used

• Aromatic hydrocarbons are the major products

• C-C bonds are broken

• Zeolite catalysts are used

Thermal cracking is when

• a slight pressure and high temperature with a zeolite catalyst produces aromatic hydrocarbons and motor fuels

• a high pressure and high temperature produce a high percentage of alkenes

• initiation, propogation and termination occur.

• polymers are made

Which catalyst is used in the catalytic cracking of alkanes?

• concentrated phosphoric acid

• iron

• nickel

• zeolite
