Question

1. Assign oxidation numbers to the carbon atoms in Benzil and Benzilic acid. According to your numbers, has an oxidation or reduction (or neither) occurred?

2. BZ’s IUPAC name is α‐hydroxy‐α‐phenyl benzene acetic acid‐1‐azabicyclo [2.2.2] oct‐3yl ester. To what atom(s) does the term “aza” refer? To what does the [2.2.2] refer?

Answer 1

Dear Student, Kindly refer to the complete solution. Feel free to ask if you face difficulty in understanding any step of the solution attached so that we can assist you in a better way.

Dear Student, The Benzil - Benzilic reactions involve a acid rearrangement ☺ & Benzil оно Le-o-on Bensilic acid I honile assigning the oxidation numbers, considel the band as an ionic bond and break it in a mannel such that more electronegative atom gets negative charge and less electroneg- lative gets positive charge. These charges on each atom acts as onidation numbers 불성 whith - +1 wir Ć - c- + c * Benzil O.No. +2 O.No. = +2 P.T.O.

Benzilic acid OH sort D.No.+3 O.NO.: +! Oxidation involves increase in oxidation number . Reduction involves decrease in oxidation nomber. This can be considered as an inteanolecular dispeoportionation reaction since one carbon atom is getting oxidised (+2 to +3) and one carbon atom is getting reduced (+& tot!). ② B23 repac name is a-hydroxy --phenye benzeneacetic acid-1-azabicyclo [2.2.2] oct-3- yl ester

The as Aza" term is used in IUPAC when carbon atom is replaced by N-atom. 12.2.2] represents the number of c-atom between two beige head atom in bicyclic compounds & c-atoms b/w bridge head atoms We have, budge head a C-atoms bus a bridge atome. g C-atoma 8/10 bridge v beidge head head atom Thus [2.2.2.] is used in IUPAC naming Best wishes !!
