Question
Chapter 5, Problem 59E
Interpretation Introduction
Interpretation:
The suggestion about mass, particle charge and a minimum number of positive particles from different elements which are obtained by
Concept introduction:
Thomson proposed that electrons are embedded in a positively charged sphere. The electrons are negatively charged subatomic particles which are a present atom of different elements. When an atom loses come electrons, it becomes a positively charged particle.

3. Consider the compounds below and determine if they are aromatic, antiaromatic, or
non-aromatic. In case of aromatic or anti-aromatic, please indicate number of I
electrons in the respective systems. (Hint: 1. Not all lone pair electrons were explicitly
drawn and you should be able to tell that the bonding electrons and lone pair electrons
should reside in which hybridized atomic orbital 2. You should consider ring strain-
flexibility and steric repulsion that facilitates adoption of aromaticity or avoidance of anti-
