Multiple Choice
When the amine RNH2 (where R is a 12-carbon alkyl chain) is neutralized with aqueous HCl,the compound RNH3+Cl- forms.Briefly predict,with reasons,the solubilities of RNH2 and RNH3+Cl- in water.
A) Both are insoluble due to the hydrophobic long carbon chain.
B) Both are soluble because both contain polar N-H bonds.
C) RNH2 is insoluble due to the long hydrophobic carbon chain,but RNH3+Cl- is soluble due to the ionic part of the compound.
D) RNH2 is soluble due to the polarity of the N-H bond.The salt is insoluble because most chloride salts are insoluble in water.
E) None of the choices are correct.
