| List-$I$ | List-$II$ |
| $(1)$ Kossel and Lewis | $(A)$ $VSEPR$ |
| $(2)$ Langmuir | $(B)$ Molecular Orbital Theory |
| $(3)$ Sidgwick and Powell | $(C)$ Covalent Bond |
| $(4)$ Heitler and London | $(D)$ Octet Rule |
| $(5)$ $F$. Hund and Mulliken | $(E)$ Valence Bond Theory |
(D) The correct matches are:
$(1)$ Kossel and Lewis proposed the $(D)$ Octet Rule.
$(2)$ Langmuir introduced the concept of $(C)$ Covalent Bond.
$(3)$ Sidgwick and Powell proposed the $(A)$ $VSEPR$ theory.
$(4)$ Heitler and London proposed the $(E)$ Valence Bond Theory.
$(5)$ $F$. Hund and Mulliken proposed the $(B)$ Molecular Orbital Theory.
Thus,the correct sequence is $(1-D, 2-C, 3-A, 4-E, 5-B)$.
