Answer :
Final answer:
The difference in bond angles between carbon dioxide and water is due to their molecular geometry and the presence of lone pairs of electrons.
Explanation:
The difference in bond angles between carbon dioxide and water is primarily due to the molecular geometry and presence of lone pairs of electrons. In CO₂, the linear shape and equal strength of the bond dipoles cancel each other out, resulting in a nonpolar molecule with bond angles of 180°. On the other hand, in H₂O, the bent shape caused by the two lone pairs on the central oxygen atom leads to an unequal distribution of charge, making it a polar molecule with bond angles deviating from ideal geometry.
