1 of 8

What reagents are needed for the conversion of an alcohol to a halogenoalkane?

Chloride: phosphorus pentachloride (PCL5), Bromide: potassium bromide (HBR) and 50% conclusion sulphuric acid(H2SO4), Iodide: Red phosphorus (P) and iodine (3I2) giving phosphorus (|||) iodide (PI3)

2 of 8

Define a chiral molecule

A molecule containing a carbon bonded to 4 different groups giving a molecule that is non super imposable on its mirror image

3 of 8

Define a racemic mix

A mixture containing equal amounts of two enantiomers

4 of 8

Why would strong interactions between ligands and the metal ion result in a colourless complex?

The energy gap is so large that energy absorbed is outside the visible region

5 of 8

How are octahedral complexes able to form?

Additional lone pairs are accommodated in vacant D orbitals

6 of 8

How is a standard hydrogen electrode set up?

I bar hydrogen gas bubbled over platinum foil dipped in 1moldm-3 hydrochloric acid

7 of 8

How can transition metals act as homogeneous catalysts?

Transition metals form various oxidation states so are able to donate and receive electrons
