sweet [91]

<u>Answer:</u> The total number of electrons that must be shared between carbon and oxygen atoms are 8.

<u>Explanation:</u>

A covalent compound is formed when sharing of electrons takes place between the atoms forming a compound.

Carbon is the 6th element of the periodic table having electronic configuration of 1s^22s^22p^2

This element requires 4 electrons to complete its shell.

Oxygen is the 8th element of the periodic table having electronic configuration of 1s^22s^22p^4

This element requires 2 electrons to complete its shell.

So, in order to complete the octet of both the elements, 2 oxygen atoms are required for 1 carbon atom.

Hence, the total number of electrons that must be shared between carbon and oxygen atoms are 8.
