The bond between carbon and hydrogen, and oxygen and hydrogen is a covalent bond.

Here's why:

* Covalent bonds form when two atoms share electrons to achieve a more stable electron configuration.

* Carbon and hydrogen have similar electronegativities (the ability of an atom to attract electrons), meaning they share electrons fairly equally in a nonpolar covalent bond.

* Oxygen is more electronegative than hydrogen, so the shared electrons are drawn closer to the oxygen atom, creating a polar covalent bond.

Here's a summary:

| Bond | Atoms | Type of Covalent Bond |

|-------------|-------------------|-----------------------|

| C-H | Carbon & Hydrogen | Nonpolar |

| O-H | Oxygen & Hydrogen | Polar |
