Both pyrrole and pyridine are aromatic compounds, and undergo electrophilic aromatic substitution (EAS). Using a resonance argum
ent, predict the regiochemistry of EAS on both pyrrole and pyridine. As part of your argument, you must draw resonance structures for the arenium ion leading to each possible regiochemistry, and compare the stabilities of the resonance hybrids. In addition, make a reasoned statement about whether you think each one would react faster or slower than benzene and why.

Answer: 4
Explanation:
Principle Quantum Numbers: This quantum number describes the size of the orbital. It is represented by n.
Azimuthal Quantum Number: This quantum number describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...
Magnetic Quantum Number: This quantum number describes the orientation of the orbitals. It is represented as . The value of this quantum number ranges from
. When l = 2, the value of
will be -2, -1, 0, +1, +2.
Given : a f subshell, thus l = 3 , Thus the subshells present would be 3, 2, 1, 0 and thus n will have a value of 4.
Also electrons give are 32.
The formula for number of electrons is .
Thus principal quantum no will be n= 4.
