(a)
Interpretation:
The condensed electronic configuration and the number of unpaired electrons in
Concept introduction:
The electronic configuration of an element tells about the distribution of electrons in the atomic orbitals. It is used to predict the physical, chemical, electrical and magnetic properties of the substance.
The condensed electronic configuration is a short way to write the configuration of elements in terms of the nearest noble gas configuration.
The electrons are filled up in accordance with three rules:
1. Aufbau principle which states that the electrons are filled up in the increasing order of their orbitals which follows as:
2. Hund’s rule which states that the pairing of electrons will not start until each of the orbitals is singly occupied.
3. Pauli’s exclusion principle states that no two electrons can have the same value of all the four quantum numbers.

For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forward
