Chapter 22, Problem 5RQ

To how many atoms is a saturated carbon atom bonded?

To determine

The number of atoms which are bonded to a saturated carbon atom.

Answer to Problem 5RQ

A saturated carbon atom is bonded to four neighboring atoms by using four single covalent bonds.

Explanation of Solution

In a saturated hydrocarbon, each carbon atom is bonded to other atoms by only single covalent bonds. For example, the chemical formula of methane is ${\text{CH}}_{\text{4}}$. It is a kind of saturated hydrocarbon as its structural formula contains only single covalent bonds.

There is one carbon atom which is linked to four hydrogen atoms in order to satisfy its valency. In total there is one carbon atom and four hydrogen atoms in methane molecule.

Therefore, a saturated carbon atom is bonded to four neighboring atoms by using four single covalent bonds.

Conclusion:

Therefore, the number of atoms which are bonded to a saturated carbon atom is four.
