Assertion : Hydrolases are the enzymes which catalyse the hydrolysis of ester, ether, peptide, glycosidic, C-C or P-N etc., bonds.
Reason : Lyases are the enzymes catalysing the linking together of 2 compounds like joining of C-O, C-N, P-O etc. bonds.

Explanation

To analyze the given question, we will break it down into two parts: the assertion and the reason.

### Step 1: Understand the Assertion
The assertion states that "Hydrolases are the enzymes which catalyse the hydrolysis of ester, ether, peptide, glycosidic, C-C or P-N bonds."
- **Hydrolases** are indeed a class of enzymes that catalyze the hydrolysis reaction. Hydrolysis is a chemical process where water is used to break down the bonds of a compound.
- Hydrolases facilitate the breakdown of various types of bonds, including ester, ether, peptide, glycosidic, carbon-carbon (C-C), and phospho-nitrogen (P-N) bonds.
- Therefore, the assertion is **true**.

### Step 2: Understand the Reason
The reason states that "Lyases are the enzymes catalysing the linking together of 2 compounds like joining of C-O, C-N, P-O bonds."
- **Lyases** are a different class of enzymes that catalyze the addition of groups to double bonds or the removal of groups to form double bonds, but they do not typically catalyze the linking of two compounds in the way described.
- The statement incorrectly describes the function of lyases. Instead of linking compounds, lyases are involved in breaking down molecules without the addition of water (i.e., they do not catalyze hydrolysis).
- Therefore, the reason is **false**.

### Step 3: Conclusion
Based on the analysis:
- The assertion is **true**.
- The reason is **false**.

Thus, the correct answer is: **Assertion is true, Reason is false.**
