Answer #1

CoH4 is given, but i assume it could be CH4 as no such COH4 is known.

CH4. is neutral, neither acidic nor basic in aqueous solution(though the solubility in water is very less)

H3PO4 phosphoric acid. when dissolved in water it shows acidic properties, turns blue litmus red. It is a tribasic acid.

H2SO4 sulphuric acid . It is a strong dibasic acid, can turn blue litmus to red.

HClO4 perchloric acid. It is one of the strongest acids, can trun blue litmus to red.

we were doing acid-base extraction lab. The mixture included a base, an acid and a neutral organic compound. So at the end of lab we have to predict what is the organic compound. this organic compound was one of these: a) 4-chlorobenzophenone b) biphenyl c) trans-stilbene d) trans-chalcone in the solubility test, the organic compound dissolve in cold hexane and ethyl acetate. it did not dissolve in water and cold methanol, but it dissolve in hot methanol. can someone predict...
