Question
Chapter 3, Problem 3.24QAP
Interpretation Introduction
Interpretation:
The output voltage of an integrator 1, 3, 5, and 7 s after the start of integration needs to be plotted.
Concept introduction:
The output voltage can be calculated as follows:
Here,
V0 = output voltage
Ri = input resistor
C = feedback capacitor
Vi = input voltage
T = time

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-
aromaticity)
