According to valence bond theory,which orbitals overlap in the formation of the bond in HCl?
A)1s on H and 2p on Cl
B)2s on H and 3p on Cl
C)1s on H and 3s on Cl
D)1s on H and 3p on Cl
E)1s on H and 4p on Cl

Question

Quizplus · Accepted Answer

In HCl molecule, hydrogen has only 1s orbital and chlorine has 3p orbital. Therefore, according to valence bond theory, the sigma bond is formed by the overlap of the 1s orbital of hydrogen and the 3p orbital of chlorine. Thus, the correct option is D) 1s on H and 3p on Cl.
