Question

Please, help me... Please answer only if you know correct answers please. if you can give me correct answers and detailed explanation, it will help me a lot to study lewis structures and resonance structures. Thanks.

Rank the following labeled bonds in order from weakest to strongest (Hnt: consider resonance!) Draw a 3D representation of the structure below (hint: use wedge-dash notation). Determine the hybridization of the atoms A and B and the types of orbitals that overlap to form bonds C and D Draw the atomic orbital energy diagram for an oxygen atom before hybridization. Then draw the atomic orbital energy diagram for the hybridized oxygen atom in dimethyl ether (CH;OCH3). Label your diagram appropriately (We did this in class with carbon in several examples.) Energy

Explanation / Answer

1. Rank of labeled bonds -

2 < 3 < 1 < 4

Because bond 1 is single bond, bond 3 have partial double bond character due to resonance, bond 1 is double bond and bond 4 is triple bond and we khow that single bond is the weakest bond and triple bond is the strongest bond.
