To determine which compound is most likely a covalent compound, let’s evaluate the properties of each compound based on the given criteria for covalent compounds:
### Criteria for Covalent Compounds:
1. Low melting and boiling points.
2. Does not conduct electricity.
### Given Data:
[tex]\[
\begin{array}{|c|c|c|c|}
\hline
\text{Compound} & \text{Melting Point} \, (^{\circ}C) & \text{Boiling Point} \, (^{\circ}C) & \text{Conducts Electricity} \\
\hline
\text{A} & -183 & -164 & \text{no} \\
\hline
\text{B} & 660 & 2467 & \text{yes} \\
\hline
\text{C} & 772 & 1600 & \text{yes} \\
\hline
\end{array}

### Analysis of Each Compound:
1. Compound A:
- Melting Point: -183 [tex]\(^{\circ}C\)[/tex]
- Boiling Point: -164 [tex]\(^{\circ}C\)[/tex]
- Conducts Electricity: No
- This compound has both low melting and boiling points and does not conduct electricity. It meets all the criteria for being a covalent compound.
2. Compound B:
- Melting Point: 660 [tex]\(^{\circ}C\)[/tex]
- Boiling Point: 2467 [tex]\(^{\circ}C\)[/tex]
- Conducts Electricity: Yes
- This compound has high melting and boiling points and conducts electricity. It does not meet the criteria for being a covalent compound.
3. Compound C:
- Melting Point: 772 [tex]\(^{\circ}C\)[/tex]
- Boiling Point: 1600 [tex]\(^{\circ}C\)[/tex]
- Conducts Electricity: Yes
- This compound also has high melting and boiling points and conducts electricity. It does not meet the criteria for being a covalent compound.
### Conclusion:
Based on the analysis, Compound A is the only one that meets the criteria for being a covalent compound. Therefore, the compound that is most likely a covalent compound is:
