Assertion: Molecular formula shows the exact number of different types of atoms present in a molecule of a compound.
Reason : Molecular formula can be obtained directly from empirical formula which represents the simplest whole number ratio of various atoms present in a compound.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Explanation

To analyze the assertion and reason provided in the question, we can break it down step by step.

### Step 1: Understanding the Assertion
The assertion states that the molecular formula shows the exact number of different types of atoms present in a molecule of a compound.

- **Explanation**: A molecular formula provides the actual number of each type of atom in a molecule. For example, the molecular formula of water is H₂O, which indicates that there are 2 hydrogen atoms and 1 oxygen atom in each molecule of water. Therefore, the assertion is **true**.
