Concept explainers
Interpretation: The curved arrows to resonance structures of benzene should be added. Also, type of arrow should be determined.
Concept introduction: When one single structure is unable to describe all the properties of single molecule, a phenomenon called resonance comes into play. This arises when two or more than two Lewis structures are possible for one molecule. All such structures are called resonating structures and have same placement of atoms in them but these have different locations of bond pairs and lone pairs. The resonating structures are inter-convertible with each other. The resultant of all the resonating or contributing structures is called the resonance hybrid.
Rules to form resonance structure are as follows:
1. Use arrow types 1 and 2 for resonance structure of anions in movement of negative charge.
2. Use only arrow type 3 to move a positive charge for resonance structure of cations.
3. The sigma bond should not be broken. Any atom must not move from its place and total number of electrons must be same in all resonance structures.

- I am having trouble on part c. It wants me to draw the resonance structure, but in mastering chem there’s no arrows available for some reason . Is there a way to draw it without the arrows and still be resonancearrow_forwardWhich of the following species (B, C,D) is a valid resonance of A? Use curved arrows to show how A is converted to any valid resonance structure.arrow_forwardSolve correctly please, need all 4 subparts ans.arrow_forward
- For 1 and 2, use curved arrows to illustrate the potential overall electron movements or bond changes, and identify the type of reaction by examining the overall chemical transformation. Show A-H bonds as needed.arrow_forwardanswer 3 and 5. PLS MAKE IT LIKE THIS WAY SO THAT I UNDERSTAND IT IONIC YES OR NO POLAR YES OR NO NON POLAR YES OR NO IMF EXIST IS..... NO EXPLANATION NEEDED.arrow_forward9) Draw the resonance contributor that corresponds to the curved, two electron movement arrows in the resonance expressions below. -I Harrow_forward
- Would you mind to check all the answer on this table because I try to understand the line bond structure and re-draw structure my homeworkarrow_forward! ( do b with explanation)arrow_forwardKindly provide a more credible answer (explanation and solution) since the ones available online are not accurate. Thank you and pls skip if unsure.arrow_forward
- For each proposed set of resonance structures: a. (E) Add curved arrows (starting from left) to show how each successive r.s. was generated. b. Cross out any resonance structures that are NOT important, and explain your reasoning.arrow_forwardAmong the resonance structures that occur in the structure below, please tell us a resonance structure that does not actually contribute to a resonance hybrid. I want the reason to be detailed.arrow_forwardA. Determine whether the curved arrow(s) shown below generate a valid or invalid resonance structure. Draw the resonance structure that would result from each properly drawn arrow and identify the arrow pushing pattern (i.e. allylic positive charge, allylic lone pair, pi bond between atoms of a different electronegativity, lone pair adjacent to a positive charge, alternating pi bonds in a ring.arrow_forward
