SUMMARY
The discussion clarifies the differences between hydrogen bonds and covalent bonds in H2O. The H2O covalent bond involves hydrogen atoms sharing electrons with oxygen, resulting in a strong bond that requires approximately 430 kJ/mol to break. In contrast, hydrogen bonds are weaker interactions between water molecules, requiring only 10 to 40 kJ/mol to break. The polarity of water, due to unequal electron sharing, leads to hydrogen bonding, where the negatively charged oxygen attracts positively charged hydrogen atoms from neighboring molecules.
