What is the relationship between bond length and resonance structures. Related questions How can I determine if and when a molecule has or needs a resonance structure? Question dc6d6.

Why does resonance occur?

What are common mistakes students make with resonance? Any double covalent bond between two given atoms is typically shorter than a single covalent bond. Studies of the O 3 and other similar molecules showed that the bonds were identical in length. Interestingly, the length of the bond is in between the lengths expected for an O-O single bond and a double bond. Resonance is the use of two or more Lewis structures to represent the covalent bonding in a molecule. One of the valid structures is referred to as a resonance structure.

It is now understood that the true structure of a molecule which displays resonance is that of an average or a hybrid of all the resonance structures. Many polyatomic ions also display resonance. The bond lengths between the central N atom and each O atom are identical and the bonds can be approximated as being equal to one and one-third bonds. Skip to main content. Covalent Bonding.
