Question
- A. They have strong ionic bonds
- B. They consist of covalent bonds
- C. They are made of metallic bonds
- D. They contain only one type of atom
Answer
The correct option is They consist of covalent bonds. This answer is correct because it matches the approved learning objective to represent single covalent bonds in small molecules using lines in the subtopic Covalent bonding.
Explanation
The correct option is They consist of covalent bonds. They consist of covalent bonds is correct because it directly supports the approved learning objective to represent single covalent bonds in small molecules using lines. This belongs to the subtopic Covalent bonding within Chemical bonds, ionic, covalent and metallic, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Covalent bonding.
Common mistake
Misunderstanding Bond Representation
Students often confuse the representation of single covalent bonds in small molecules by using dots instead of lines.
To fix this, remember that single covalent bonds should be represented using lines, as this indicates the sharing of pairs of electrons between atoms.
