A carbon atom can form 4 single covalent bonds

Two covalent bonds attach both Oxygen atoms to the Carbon atom. You should have figured that out using the Lewis structure.

A single carbon atom can form a maximum of four covalent bonds. This is because carbon has four valence electrons available for bonding.
Single, double, and triple covalent bonds
In an alkane, each carbon atom forms four covalent bonds with other atoms. This means that each carbon atom in an alkane molecule is bonded to two other carbon atoms and two hydrogen atoms, resulting in a total of four covalent bonds per carbon atom.
Carbon form generally covalent bonds; ionic bonds are rare.
maximum of four (single) covalent bonds per carbon
In a diamond lattice, each carbon atom forms four covalent bonds with its neighboring carbon atoms. Therefore, there are four covalent bonds in a diamond lattice structure.
In an alcohol molecule, there are usually two types of chemical bonds - covalent bonds between carbon and oxygen, and hydrogen bonds between hydrogen and oxygen atoms. Each carbon atom forms a single covalent bond with the oxygen atom, while the hydrogen atoms form single covalent bonds with the oxygen atom.
A carbon atom can form up to four covalent bonds. This is because carbon has four valence electrons, which it can share with other atoms through covalent bonding to achieve a full outer shell of electrons.
