Which molecule has the shortest single bond?

Question

Quizplus · Accepted Answer

The molecule with the formula H₂ refers to H2S, which is not correctly represented here. However, considering the options, the shortest single bond among the given molecules would typically be found in a molecule with the smallest non-hydrogen atoms due to less electron cloud repulsion and a stronger bond. However, none of the given molecules directly match common representations, and the question seems to involve a misunderstanding or typo. Typically, HF would have the shortest bond length due to fluorine being the smallest atom listed, but the representation given for choice A does not correspond to a recognized chemical species. If we correct for the apparent confusion and focus on known molecules, HF would be expected to have the shortest bond due to the small size of fluorine, which allows it to form a very short bond with hydrogen. However, without a correct representation of choice A, this question's premise is flawed.
