Vedclass · Answer

(B) $1$. Naphthalene is a neutral organic compound,while tetrahydroisoquinoline is a basic amine.$2$. When treated with $HCl$,the basic tetrahydroisoquinoline reacts to form a water-soluble salt (tetrahydroisoquinolinium chloride),which enters the aqueous layer.$3$. Naphthalene remains in the diethyl ether layer. Evaporation of the ether layer yields $A =$ naphthalene.$4$. The aqueous layer contains the salt of the amine. Adding $NaOH$ makes the solution basic,converting the salt back to the free base (tetrahydroisoquinoline),which is organic-soluble and moves into the ether layer.$5$. Evaporation of this second ether layer yields $B =$ tetrahydroisoquinoline.$6$. The remaining aqueous layer contains inorganic salts like $NaCl$ formed during the neutralization. Evaporation of this layer yields $C =$ inorganic ions such as $Na^{+}$ and $Cl^{-}$.
