1.

What is the structural formula?
- A.
  
  The actual arrangement of atoms in a molecule
- B.
  
  The types of atoms in a molecule
- C.
  
  The number of atoms in a molecule
Correct Answer
A. The actual arrangement of atoms in a molecule

Explanation
The structural formula refers to the actual arrangement of atoms in a molecule. It provides a visual representation of how the atoms are bonded together and the spatial arrangement of the molecule. This is different from the types of atoms in a molecule, which refers to the elements present, and the number of atoms in a molecule, which refers to the count of each type of atom. The structural formula provides more detailed information about the molecular structure.

True or False?Compounds may have the same structural formula but different molecular formula.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Compounds may have the same molecular formula but different structural formula.
They can have the same numbers of the same molecules, but arranged in different ways.

Rate this question:
3.

Complete the following sentence:_______ are compounds than can have the same molecular formula but be arranged in different ways (have different structural formulas).

Correct Answer
Isomers
Structural isomers

Explanation
Isomers are compounds that can have the same molecular formula but be arranged in different ways, known as different structural formulas. This means that they have the same number and types of atoms, but the atoms are arranged differently within the molecule. Structural isomers specifically refer to isomers that differ in the connectivity of their atoms, resulting in different structural formulas.

4.

Complete the following sentence:_______ have the same molecular formula and sequence of bonded atoms, but their atoms are arranged differently in three-dimensional space.

Correct Answer
Stereoisomers

Explanation
Stereoisomers are compounds that have the same molecular formula and sequence of bonded atoms, but their atoms are arranged differently in three-dimensional space. This means that they have the same number and types of atoms, but they differ in how these atoms are arranged in space. This arrangement can result in different physical and chemical properties for stereoisomers, even though they have the same chemical formula.
