Question

multiple answer 1 point protonating an amine with hcl leads to which of the following transformations? conversion to an ammonium chloride salt formation of a neutral amine increased solubility in water increased solubility in ether

Explanation:

When an amine is protonated by HCl, the lone - pair of electrons on the nitrogen atom of the amine accepts a proton ($H^+$) from HCl. This results in the formation of an ammonium ion ($RNH_3^+$), which combines with the chloride ion ($Cl^-$) to form an ammonium chloride salt. Ammonium salts are ionic compounds and are more soluble in water due to ion - dipole interactions with water molecules. A neutral amine is not formed as the amine is protonated. Ether is non - polar and ionic ammonium salts are less soluble in non - polar solvents like ether.

Answer:

A. Conversion to an ammonium chloride salt
C. Increased solubility in water
