Question

which option below is correct representation for a hydrogen bond? a) diagram a b) diagram b c) diagram c d) diagram d

Explanation:

Hydrogen bonds occur between a hydrogen atom (covalently bonded to a highly electronegative atom like oxygen) and another electronegative atom. In option C, the dashed line (representing the hydrogen bond) is between a hydrogen (attached to oxygen) and another oxygen atom. Option A has no oxygen (so no hydrogen - bond - relevant electronegative atoms for the context of hydrogen bonding in such structures). Option B has the dashed line in an incorrect position (not between the appropriate hydrogen and electronegative atom). Option D has the hydrogen - bond - like dashed line in a non - standard and incorrect orientation for hydrogen bonding in these molecular representations.

Answer:

C. Diagram C
