hexane
insoluble
naphthol in water
2.5 NaOH, HCl
what is the naphthols main solvent
HCl
aniline is only soluble to what solvent
they are both polar making them dissolvable as like dissolves like
alanine, petroleum ether, formalin, acetic acid, hexane was soluble because?
they are hydrophobic, and also they have strong and stable molecules which makes them hard to break down
non-polar compounds are not immiscible in water because?
Alanine
is both acidic and basic due to the presence of zwitterions
because of the presence of aldehydes
why is formalin neutral?
they both do not have any functional groups, they neither donate nor accept any protons
why is hexane, petroleum ether neutral?
to know the presence of functional groups
why is the purpose of testing their acidity or basicity?
the naphthalene ring present is hydrophobic
why is naphthol slightly soluble
it has a large aromatic ring which is hydrophobic and has a weak polarity causing to not react to NaOH, it reacts with HCl and from anillium ions
why is aniline only soluble in HCl
it has butanol chains which hydrophobic and can react with water to form hydrogen bonds due to tis hydroxyll group.
why is n-butanol non soluble to all solvent
