Possible Isomers for Disubstituted Borazine

Explanation:

Borazine, also known as inorganic benzene, is a six membered ring in which three boron atoms are alternated with three nitrogen atoms. Each of the boron and nitrogen atoms is attached with a hydrogen atom. The possible isomers for disubstituted borazine are:

1. Ortho isomer: In this isomer, both the substituents are attached to the adjacent atoms of the borazine ring. This leads to the formation of a chiral molecule with two enantiomers.

2. Meta isomer: In this isomer, both the substituents are attached to the atoms that are separated by one carbon atom in the borazine ring. This also leads to the formation of a chiral molecule with two enantiomers.

3. Para isomer: In this isomer, both the substituents are attached to the atoms that are opposite to each other in the borazine ring. This leads to the formation of a non-chiral molecule.

4. Cis-trans isomer: In this isomer, the two substituents are attached to the borazine ring in such a way that they are either on the same side (cis) or on the opposite side (trans) of the ring. This leads to the formation of a non-chiral molecule.

Hence, the possible isomers for disubstituted borazine are 4.
