Select the incorrect statement :

Options

A. Silicon does not form an allotrope like graphite because of its no tendency of multiple bond formation.
B. Catenation tendency is greater in `C` than in `Si`.
C. `CO` is stable in nature but `SiO` does not
D. None of these

Answer

To solve the question of selecting the incorrect statement from the provided options, we will analyze each statement step by step.

### Step 1: Analyze the First Statement
**Statement:** Silicon does not form allotropes like graphite because it has no tendency to form multiple bonds.

**Explanation:**
- Silicon, being in the same group as carbon, does not form allotropes like graphite due to its inability to form strong multiple bonds.
- The bond strength in silicon-silicon bonds is weaker than that in carbon-carbon bonds, which is why silicon cannot form macromolecular structures like graphite.

**Conclusion:** This statement is correct.

### Step 2: Analyze the Second Statement
**Statement:** Catenation tendency is greater in carbon than in silicon.

**Explanation:**
- Catenation refers to the ability of an element to bond with itself to form long chains.
- Carbon has a smaller atomic size and stronger carbon-carbon bonds, allowing it to catenate effectively.
- In contrast, silicon has a larger atomic size and weaker silicon-silicon bonds, resulting in a lower tendency for catenation.

**Conclusion:** This statement is also correct.

### Step 3: Analyze the Third Statement
**Statement:** Carbon monoxide is stable in nature, but silicon oxide is not stable in nature.

**Explanation:**
- Carbon monoxide (CO) is stable due to effective overlapping of its 2p orbitals, resulting in strong bonding.
- Silicon oxide (SiO2), on the other hand, does not have the same effective overlapping due to the larger size of silicon, leading to weaker bonds and instability in certain forms.

**Conclusion:** This statement is correct as well.

### Step 4: Determine the Incorrect Statement
After analyzing all three statements, we find that:
1. The first statement is correct.
2. The second statement is correct.
3. The third statement is correct.

Since all statements provided are correct, we conclude that there is no incorrect statement among the options presented.

### Final Answer
**None of the statements are incorrect.**
