Write the electronic configuration of HF, HCl, and LiF molecules, hence obtain the bond orders. Draw the schematics of the molecular orbitals and atomic orbitals for each molecule.

The electronic configurations of the molecules HF, HCl, and LiF can be derived by considering the atomic orbitals of their constituent atoms. Each molecule forms covalent bonds by sharing electrons, and the bond order can be determined from the molecular orbital theory.

HF (Hydrogen Fluoride):

• Hydrogen (H) has the electron configuration: 1s¹.

• Fluorine (F) has the electron configuration: ______ ___ ________ ______ ____ _________ __________ ___ ___ __________ _________.
