okay. this is some basic knowledge about chemistry.
firstly, ethanamine is a gas at room temperature, and like all amines, it's alkali
this information is used to solve for compound I for question 9 from the deductive questions worksheet the teachers gave for revision.(the gas evolved is NOT ammonia, but ethanamine.)
secondly, METHANOIC ACID gives a positive test with tollen's reagent.(even though this clash with our knowledge that tollen's reagent only react with aldehydes, just note the exceptions. also, it reacts with 1-alkynes.)
this is used to solve the deductive question of the acidic product after hydrolysis of the first compound.(question 4a from the LAST chem test, i think paper 3, the one returned unmarked.)
that's about all. of course, i have my sources to cross refer to, to prove that these are reliable knowledge. here they are
