10cm3 of an alkane was sparked with 100cm3 of excess oxygen. The resulting gases were cooled to room temperature and had a volume of 75cm3. Exposure of the gases to NaOH reduced the volume to 35cm3. Which alkane was used?
Butane

In the presence of UV light, methane reacts with excess chlorine. Which compound is formed?
CCl4
5 of 13
Define the term Secondary Halogenoalkane.
A halogenoalkane which has two carbon atoms directly bonded to the carbon atom that is bonded to the halogen.
6 of 13
Which compound has the lowest boiling point?
1-iodopropane
7 of 13
Which equation best shows the reaction between sodium hydroxide and 2-chlorobutane?
Solid phosphorus pentachloride is added to butan-2-ol. What might be observed?
Pungent gas

Why would a pear shaped flask be used in reflux?
Condensed droplets run back into the liquid.
10 of 13
What is meant by 'in situ?'
The substance is not directly added, safer reagents which produce the substance are added.

2-methylpropan-2-ol is refluxed with acidified potassium dichromate. Nothing is observed. Explain why.
The alcohol is a tertiary alcohol and so there aren't enough hydrogen atoms to create water.
