The Gabriel Phthalimide synthesis is a method used to synthesize primary amines from potassium phthalimide. It involves the formation of a phthalimide salt, followed by alkylation and hydrolysis. This synthesis is particularly useful for producing primary aliphatic amines, but we are tasked with finding aromatic amines. Let's explore possible structures for C8H11N.
We need to identify isomeric aromatic amines here. An aromatic amine contains an aryl group attached to the nitrogen atom. For C8H11N, the aromatic ring is benzene (C6H5), meaning one of the hydrogen in C6H6 is replaced by NH2, leading to C6H5NH2, or aniline. The remaining C2H6 is present in substituents on the benzene ring.
Possible C2H6 substituents could include two methyl groups. These can be distributed around the benzene ring in different positions:
1,2-positions (ortho-xylene): 2,3-dimethylaniline
1,3-positions (meta-xylene): 3,4-dimethylaniline
1,4-positions (para-xylene): 2,5-dimethylaniline
2-methyl-3-methylaniline
2-methyl-4-methylaniline
3-methyl-5-methylaniline
Each configuration provided above forms a unique isomer. Overall, there are six possible isomers:
2,3-dimethylaniline
2,4-dimethylaniline
2,5-dimethylaniline
3,4-dimethylaniline
2-methyl-3-methylaniline
3-methyl-5-methylaniline
The aromatic amines listed are primary as required by Gabriel Phthalimide synthesis. The total number of isomeric aromatic amines is indeed 6.
This computed value is within the range 6,6 as expected, confirming the solution's validity.
