How many single bonds are there in a molecule of CO2?
- A
None
- B
1
- C
2
- D
3
- E
4
In a molecule of carbon dioxide (CO2), there are no double bonds or single bonds as in organic molecules. Instead, it consists of one carbon atom double-bonded to two oxygen atoms. Each of these bonds is a double bond, not a single bond or triple bond. Here's a simplified structural representation of CO2
In this representation, the lines between the atoms represent the double bonds. There are no single bonds (one line) or triple bonds (three lines) in CO2.
So, the correct answer to your question is A
This is correct. CO2 only has double bonds between carbon and oxygen atoms, and no single bonds.
This is incorrect. There are no single bonds in CO2. The molecule consists of two double bonds.
This is incorrect. While there are two bonds in CO2, both are double bonds, not single bonds.
This is incorrect because it implies the existence of three single bonds, which is not present in CO2. All bonds are double bonds.
This is incorrect, as CO2 does not contain four bonds of any kind. It only contains two double bonds.
