100

What is the general formula of the alkanes?

CnH2n+2

100

Name three types of addition reaction that alkenes can do (eg. hydrogenation)

halogenation

hydrohalogenation

hydration

polymerization

100

What is the name of the functional group that all alcohols contain?

hydroxyl group

200

Name this molecule

Propanone

200

Balance the combustion reaction for butane

200

Name the test for unsaturation

The bromine test

200

What does the term "tertiary alcohol" mean?

An alcohol where the -OH group is attached to a carbon with 3 hydrocarbon constituants.

300

Name this compound

1-Chloro-2,2-dimethylpropane

300

What is the name of the type of fission involved in the initiation step of free radical substitution?

homolytic fission

300

Which part of an alkene is the most electron rich area and why?

The C=C double bond, because of the pi bond (sideways overlap of p orbitals) 

300

Balance the combustion reaction for ethanol

C2H5OH + 3 O2 → 2 CO2 + 3 H2O

400

Draw 5-bromo-2,4-dimethylhex-1-ene

400

What is a free radical?

An atom (or molecule) with an unpaired valence electron

400

Name the conditions needed for hydrogenation

Nickle catalyst and 150 degrees celcius

400

What is the major product of the reaction of propanoic acid and methanol?

methyl propanoate

500

Draw 2-Methyl-4-penten-2-ol

500

Why does the boiling/melting point of the alkanes increase as the number of carbons increase?

Longer molecules have increased intermolecular (london dispersion) forces between them. This means there are more forces of attraction to break- requiring more energy, and therefore more heat

500

Describe markovnikovs rule

when an asymmetrical reagent is added to an asymmetrical alkene, then the negative half of the reagent will attach to the carbon atom containing fewer hydrogen atoms (allow equivalent description)

500

Name the products of the oxidation of each class of alcohol and suggest how to obtain them (including a names oxidizing agent).

Oxidize the alcohol with potassium dichromate/ potassium manganate

Primary- aldehyde (distillation) then carboxylic acid (reflux)

Secondary- ketone

Tertiary- no reaction
