Answer:
A double covalent bond.
Explanation:
A double covalent bond forms between two oxygen atoms.
A double covalent bond is when two pairs of electrons are shared between the atom. Usually, there is only one pair, rather than two pairs.
The electrostatic attractive interaction between the same or different elements is called bonds. A nonpolar covalent is formed between two oxygen atoms. Thus, option a is correct.
A chemical bond that involves the mutual sharing of electrons between the outer valence shell of the elemental atom is called a covalent bond. The covalent bonds are of two types namely polar and non-polar.
The polar covalent bond is the unequal sharing of the electrons in the outer shell due to differences in electronegativities. The non-polar covalent bond is formed between the same or different elements in a compound.
In a non-polar covalent bond like two oxygen atoms, the valence electrons are shared equally and have negligible electronegativity differences.
Therefore, option a. two oxygen atoms form a nonpolar covalent.
