Which compound contains only non polar covalent bonds? o2 co2 h2o no3

Non-polar covalent bond is present in

Explanation:

Non-polar bond is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: etc..

A polar covalent bond is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. For Example: etc..

Hence, from the given options, a non-polar bond is formed in molecule.
