Which of the following compounds contains both ionic and covalent bonds?

Options

A. `CH_2Cl_2`
B. `CHCl_3`
C. `NaClO_4`
D. `PCl_3`

Answer

To determine which of the given compounds contains both ionic and covalent bonds, we need to analyze the nature of the bonds in each compound. Here’s a step-by-step solution:

### Step 1: Understand the Types of Bonds
- **Ionic Bonds**: Formed between metals and non-metals through the transfer of electrons, resulting in the formation of cations and anions.
- **Covalent Bonds**: Formed between non-metals through the sharing of electrons.

### Step 2: Identify the Compounds
Assuming we have a list of compounds (not provided in the question), we need to examine each one to see if it contains both ionic and covalent bonds.

### Step 3: Analyze Each Compound
1. **First Compound**: Check if it contains both a metal (which can form cations) and a non-metal (which can form anions). If it does not contain both, it cannot have both types of bonds.

2. **Second Compound**: Again, check for the presence of both a metal and a non-metal. If it only contains non-metals, it will only have covalent bonds.

3. **Third Compound**: Look for a metal and a non-metal. If it has a metal that can form a cation and a non-metal that can form an anion, it is likely to have ionic bonds. Additionally, check if there are covalent bonds present within the non-metal components.

### Step 4: Confirm the Presence of Both Bonds
- For the compound that contains both a metal and a non-metal, analyze its structure:
- Identify the cation (metal) and anion (non-metal).
- Look for any covalent bonds within the anion itself (e.g., in polyatomic ions like sulfate or nitrate).

### Step 5: Conclusion
After analyzing the compounds, if one compound contains both ionic bonds (from the metal and non-metal interaction) and covalent bonds (within a polyatomic ion), that compound is the correct answer.

### Final Answer
The compound that contains both ionic and covalent bonds is the one identified in the analysis, which is likely the third option mentioned in the video.
