Which of the following is most soluble in water?

#CH_3CH_2CH_2CH_2CH_2OH#
#CH_3CH_2CH_2COOH#
#CH_3CH_2CH_2CH_2NH_2#

Answer 1

All the molecules contain a polar group. However, the molecule that should be most soluble in water is propanoic acid. Why?

Since butanoic acid has the shortest pendant alkyl chain, we would anticipate that it will have a higher aqueous solubility for this reason alone.

You should research the literature as a physical scientist to determine whether this prediction is accurate.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
