A

heat, ethanol, NaOH

24
Q

conditions for ester

A

heat, H2SO4

25
Q

test for carboxylic acid

A

reacts with OH and H2SO4 to create an ester (forms a sweet-smelling compound)

26
Q

test for unsaturation

A

Add Br2
red-brown colour goes away if the compound is alkene

27
Q

test for acids

A

if its acidic, it will react with sodium hydrogen carbonate to evolve CO2
