A Lewis structure and resonances for this NO 2 Cl has to be written. Concept Introduction: Lewis structures otherwise known as Lewis dot diagrams or electron dot structures. The bond between atoms and lone pairs of electrons that is present in the molecule. Lewis structure represents each atom and their position in structure using the chemical symbol. Excess electrons forms the lone pair are given by pair of dots, and are located next to the atom. Resonance structure is two forms of a molecule where the chemical connectivity is the same but the electrons are distributed differently around the structure. Generally put double headed arrows between two resonance structures.

Question

Write two resonance structures for the formate ion, HCO2‒. (The hydrogen and both oxygen atoms are bonded to the carbon.) What do these structures predict about the carbon-oxygen bond lengths of the formate ion? What do these structures predict about the electrical charge on the oxygen atoms?

10.) The structural formula of a certain aldehyde (related to formaldehyde) is H3C-CH2-CHO. Draw a Lewis structure for this aldehyde and determine the number of bonds present. Note that a single or a double or a triple bond counts as one bond. Write the number, not the word.

What possible error(s) exist in the Lewis structure (assume we are trying to represent the best possible Lewis structure for the NO₂S ion knowing N is the central atom in this polyatomic ion)? [:ö==S: N= CO :O: The best structure would have double bond and two lone pairs on each oxygen atom and a single bond with three lone pairs on the sulfur. There are no errors. This is the best possible structure. The Lewis structure above does not minimize formal charges, thus is the not the best possible structure. The nitrogen atom has an expanded octet, and this structure is impossible. The Lewis structure contains the wrong number of electrons, thus this structure is impossible.
