Draw all of the good resonance structures for the benzyl cation
these are the 3 arenium cations:
c) Draw resonance structures of all the arenium cation intermediates and use them to explain the stability trend (obtained using B3LYP/6-31G(d)) of the three optimized regioisomeric arenium cation intermediates. (7 pts) m cations by swapply IT UNU Br Br Br NOZ (in situ) NO2 ON H NO2 CA C1 arenium cations
Three major contributing resonance structures are possible for the
following cation. One is given below. Draw the remaining structures
(in any order), including nonbonding electrons and formal
charges
Three major contributing resonance structures are possible for the following cation. One is given below. Draw the remaining structures (in any order), including nonbonding electrons and formal charges.
2. (9 points) Draw the significant resonance structures for the following molecular cation: CH2 Haco
Four resonance structures of the following cation are possible. Two resonance forms are given below, but they are incomplete. Complete the given structures by adding nonbonding electrons and formal charges. Draw the two remaining resonance structures (in any order), including nonbonding electrons and formal charges HaC Ha H3 Which structure is the most stable (lowest energy) resonance contributor?
4) Provide all the Resonance structures of the Cycloheptatrienyl Cation, using arrows show the flow of electrons (delocalization) in each resonance structure. (2 points)
1. Please draw all resonance structures (if there are any, not all structures may have resonance structures) for the carbocations A-E (make sure you use resonance arrows (<->). Then circle the carbons that can react with a nucleophile in a SN1-type reaction.
(a) Draw two resonance structures of the cation shown below,
shifting only one electron pair in each step. Be sure to include
the formal charge on structures B and C.(b) Use curved-arrow notation on the given structure A to show its
conversion to structure B, and then on structure B to show its
conversion to structure C.
please provide explannation of the process, thanks.
3) Resonance Structures: Draw all of the resonance structures for the product of the reaction shown and label major and minor resonance forms. H-O H

Resonance Structures. Draw one reasonable
resonance structure for each of the following.
Resonance Structures. Draw one reasonable resonance structure for each of the following. More Resonance, Structures, Draw all reasonable resonance structure for the following. Circle the r.s. that contributes more to the hybrid. If two or more contribute equally, circle all.
Computational comparison of the structures of the benzyl cation (A) and singlet phenyl carbene (B) indicate a much greater degree of double-bond character for the exocyclic bond in A than in B. Provide a rationale for this difference, both in VB and MO terminology.
