Free notes + solved JEE problems for this lesson: https://rankdeterminant.com/go/yt-che... This chapter:    • Covalent Bonds, Resonance and Polarity | J...   All lessons of this unit:    • Chemical Bonding & Molecular Structure | J...   Bond parameters explained for JEE: bond length as the sum of covalent radii, bond angle, bond enthalpy in the gas phase, why the two O–H bonds of water need 502 and 427 kJ/mol and the average 464.5, how a higher bond order gives a shorter and stronger bond, why F2 is weaker than Cl2, and two solved problems including the enthalpy change of H2 + Cl2 from bond enthalpies.
