Answer 1
At first it’s confusing what you’re talking about..
totally soluble or miscible? So I am here mentioning for each
compound.
for ethanol –
The unique solubility of ethanol is mainly due to its
versatile nature as it has both a polar end and a non-polar end. hexane,
which has no hydrogen group and is nonpolar, is not
soluble or miscible with water, which is the most polar
substance. But since ethanol has a non-polar hydrocarbon chain and
a polar OH group, is soluble and miscible with water and
also miscible with hexane.
Water solubility-
methanol and propanol are miscible… like the carbon chain
increases the hydrophobic part also increases and the solubility in
the water decreases. then 1-pentanol will be less soluble in water.
solubility in hexane-
As the number of carbons increases, the solubility of alcohol in
hexane increases for the same reason.
I hope this answer will be useful to you. Thanks
