Analysis of Compound Structures: Same Compound, Structural Isomers, or Different Compounds?
Understanding Compound Structures
Compound 1: C H 3 C H (C H 3) C H 2 C H 3
Compound 2: C H 3 C H 2 C H (C H 3) C H 3
Compound 3: C H 3 C H 2 C H (C H 3) C H 2 C H 3
Compound 4: C H 3 C H (C H 3) C H (C H 3) C H 3
Pairs Analysis
Pair A: Compound 1 and Compound 2
These two compounds are considered structural isomers as they have the same molecular formula but differ in atom arrangement.
Pair B: Compound 3 and Compound 4
These compounds are different compounds since they have distinct molecular formulas.
Question:
What is the relationship between the compound structures in the pairs A and B?
Answer:
Compound 1 and Compound 3 are structural isomers as they have the same types and quantities of atoms but with different arrangement. Compound 2 and Compound 4 are different compounds as they possess various types and quantities of atoms.
Explanation: Pair A consists of structural isomers where the atoms are arranged differently but have the same molecular formula. Pair B involves distinct compounds with differing amounts and placements of atoms, resulting in unique compounds.
