6.3 ANALYSIS

Reagents = bromine water Observation = add few drops of bromine water, shake Result = orange to colourless

Reagents = aqueous silver nitrate and ethanol Observation = add reagents Result =

Reagents = 2,4- DNP (bradys reagent) Observation = add reagent Result = orange percipitate forms

Reagents = tollens reagent Observation = add reagent Result = silver mirror coating forms

Reagents = acidified potassium dichromate Observation = distill for primary alcohols, then excess reagent and strong reflux for primary alcohols, reflux for secondary alcohols Result = colour change from orange to green

Reagents = carbonate ion and pH probe Observation = check pH is that of a weak acid, add carbonate ion Result = no effervesence, no reaction with carbonate ion

Reagents = reactive metal/metal carbonate and pH probe Observation = check pH is that of a weak acid, add reactive metal Result = effervensence produced as carboxylic acid reacts

• Metal/glass covered in absorbant chemical (aluminum oxide/silicone dioxide)

• An organic liquid solvent

• A solid/liquid coating on a coiled tube

• An unreactive carrier gas

• The relative concentration of that chemical in the mixture

• an internal standard for carbon and proton NMR chemical shift

• An isotope of hydrogen that does not produce signals on a proton NMR as it doesnt contains protons

• CDCl3 • D2O

• Used as a solvent

• Used to identify OH and NH protons by exchanging protons so that their signals do not show up when D2O is shook vigerously in sample

• the number of different environments

• the number of hydrogen atoms on adjacent carbon atoms • (n+1)

• the number of hydrogen atoms in that environment
