(A) Gabriel Phthalimide synthesis is used for the preparation of primary aliphatic amines. It involves the reaction of potassium phthalimide with an alkyl halide followed by alkaline hydrolysis.It cannot be used for the preparation of aromatic amines because aryl halides do not undergo nucleophilic substitution with the anion formed by phthalimide.Therefore,only those amines with the formula $C_8H_{11}N$ that have the $-NH_2$ group attached to an aliphatic carbon (i.e.,primary aliphatic amines) can be synthesized by this method.The isomers of $C_8H_{11}N$ that are primary aliphatic amines are:$1$. $C_6H_5-CH_2-CH_2-NH_2$ ($2$-phenylethanamine)$2$. $C_6H_5-CH(CH_3)-NH_2$ ($1$-phenylethanamine)$3$. $o-CH_3-C_6H_4-CH_2-NH_2$ ($2$-methylbenzylamine)$4$. $m-CH_3-C_6H_4-CH_2-NH_2$ ($3$-methylbenzylamine)$5$. $p-CH_3-C_6H_4-CH_2-NH_2$ ($4$-methylbenzylamine)There are $5$ such isomers that can be synthesized by this method.

Number of isomeric aromatic amines with molecular formula $C_8H_{11}N$,which can be synthesized by Gabriel Phthalimide synthesis is $.........$.
