1

Acidified sodium dichromate (or potassium dichromate)

Reflux in excess

Primary alcohol → Carboxylic acid

Secondary alcohol → Ketone

Aldehyde → Carboxylic acid

2

Acidified sodium dichromate (or potassium dichromate)

Distil

Primary alcohol → aldehyde

3

Sodium hydroxide solution

Warm

Haloalkane → Alcohol

4

Bromine water

RTP

Alekene →  dibromoalkane

5

Conc solphuric acid or phosphoric acid

Reflux

Alcohol → Alkene

6

Water and phosphoric acid

High temperature and high pressure

Alkene to a alcohol

7

Halogen

UV light

Alkane to a haloalkane

8

Name the 3 most important greenhouse gases

Carbon dioxide

Water vapour

Methane

9

List 2 factors which determine a gas' contribution to global warming

How abundant the gas is.

 

The type of bonds present in the molecule e.g. a double bond will adsorb more

10

List 3 consequences of global warming

-Rising sea levels

-Unpredictable weather (crop yields)

-Climate change

11

Describe a way to minimise climate change

CCS (carbon, capture, storage)

Capture the CO2 before it gets into the atmosphere. 

1. Bury it deep into the ocean or oil fields under ground.

2. Or react it with an alkali to make a solid rock

 

12
