Question

Quizplus · Accepted Answer

Ethylamine is the smallest molecule among the options given, and therefore, it can form stronger hydrogen bonds with water molecules. This ultimately leads to a higher solubility in water. The other options have longer hydrocarbon chains, which decrease the polarity of the molecule and make it less soluble in water. Pentylamine has a longer chain than any of the other options and is expected to have the lowest solubility among the given options.
