Concept explainers
(a)
Interpretation:
Why benzene fails to react under the given reaction conditions has to be explained.
Concept Introduction:
Radical reaction: It is reacting to electron octet of valence shell.
A radical can break a bond in another molecular and abstract a partner with an electron, giving substitution in the original molecule.
A radical can added to an
Radical chain reaction:
Initiation reaction:
Chain propagation:
Chain termination:
It is a change in enthalpy of a hemolysis reaction at absolute zero where a molecule is broken down into two free radicals.
(b)
Interpretation:
Why the bond dissociation enthalpy of a
Concept Introduction:
Hybridization: It is the mixing atomic orbitals into new hybrid orbitals with different energies, shapes, etc., than the component atomic orbitals suitable for the paring of electrons to from chemical bonds in valance bond theory.
