The following solution is suggested to handle the subject “1. Identify each pair of compounds as constitutional isomers, stereoisomers, identical molecules, or other. (a) stereoisomers…“. Let’s keep an eye on the content below!

Question “1. Identify each pair of compounds as constitutional isomers, stereoisomers, identical molecules, or other. (a) stereoisomers…”

Answer

Isomers are pairs that contain the same empirical formula, but have different atomic arrangements or spatial orientations.

1. The connectivity of the atoms within a molecule is what distinguishes constitutional isomers.

2. Stereoisomers are different in how they arrange atoms within a molecule.

There are two types of stereoisomers, enantiomers or diastereomers. Enantiomers are a pair of compounds that are not superimposable mirror images. Diastereomers is a pair of compounds that does not have a mirror image.

3. Identical molecules refer to a pair of molecules that have no special relationship to each other.

Below is a block diagram of the explanation.

Part 1.a

Two compounds have different structural formulas.

Relationship between two chemical formulae

Part 1.b

Two compounds have different structural formulas.

The relationship between two chemical formulae

Below is a list of the positions of substitutes in the two compounds.

The relationship between pairs that use the position of substituteents is:

1, 3-substitution, 1, 4-substitution: Constitutional Isomers

Part 1.c

In part c, draw the chemical structures of each compound.

The relationship between two chemical formulae

Below is a list of the positions of substitutes in the two compounds.

The relationship between pairs that use theposition of substituteents is:

Stereoisomers: 1, 2-substitution, 1, 2-substitution

The spatial arrangement of atoms is:

Part 1.d

The chemical structures of the compounds.

The relationship between two chemical formulae

The substituent positions in the compounds are:

The relationship between pairs of compounds that use substituent positions is:

Stereoisomers: 1,3-substitution, 1,3-substitution

The spatial arrangement of atoms can be described as:

Ans: Part 1.a

Part 1.b

Part 1.c

Part 1.d

Conclusion

Above is the solution for “1. Identify each pair of compounds as constitutional isomers, stereoisomers, identical molecules, or other. (a) stereoisomers…“. We hope that you find a good answer and gain the knowledge about this topic of science.
