What will alkanes, alkenes and aromatics do to bromine water?
alkanes will deolourise bromine water, but alkenes and aromatics will create no visible change
2 of 17
What is reated when carboxylic acids and alkanes disolve in water?
carboxylic acids create a weakly acidic solution but alkanes create a weak alkali
3 of 17
Do alcohols and carboxylic acids react with Na?
yes, they produce Hydrogen gas
4 of 17
What will carboxylic acids do in Na2CO3?
react with it to produce CO2 gas

react to produce a red-orange precipitate
6 of 17
Do carboxylic acids and alcohols react with Brady's reagent?
no

What happens to aldehydes and ketones in Tollens reagent?
Aldehydes create a silver precipitate; Ketones have no visible change
8 of 17
Can Alcohols, Aldehydes and Ketones be oxidised with pottassium dichromate?
Primary alcohols, secondary alcohols and aldehydes can be and will change from an orange to a green solution; Tertiary alcohols and ketones will not react
9 of 17
How can Carboxylic acids form esters?
in a reaction with ethanol and a conc H2SO4 catalyst

What precipitate will Fluoroalkanes form when nitric acid and silver nitrate solution is added?
no precipitated, as AgF is water soluble.
11 of 17
What precipitate will Chloroalkanes form when nitric acid and silver nitrate solution is added?
A white precipitate, which disolves in dilute ammonia
12 of 17
What precipitate will Bromoalkanes form when nitric acid and silver nitrate solution is added?
Cream precipitate, which disolves in conc ammonia
13 of 17
What precipitate will Iodoalkanes form when nitric acid and silver nitrate solution is added?
Yellow precipitate, which won't disolve in either dilute or conc ammonia
14 of 17
How do acyl chlorides react with AgNO3?
vigorously to form a white AgCl precipitate
15 of 17
How do amines and amino acids react with copper (II) ions and excess ammonia?
Amines and most amino acids react to produce a dark-blue soluble complex, but aromatic amines tend to form green insoluble complexes.
16 of 17
Why does adding hydroxide ions to an amine cause the indicator to change colour more rapidly than with an amino acid?
There is no carboxylic acid group to react with the alkali
