Concept explainers
(a)
Interpretation: An explanation for higher stability of triphenylmethyl radical than other radicals is to be stated.
Concept introduction: The delocalization of lone pair or free electrons from one place to another is known as resonance. The stability of compound depends upon the number of resonating structures. More the resonating structures of compound more will be its stability.
(b)
Interpretation: The dimerization of two triphenylmethyl radicals to form A is to be represented by the use of curved arrow notation.
Concept introduction: The delocalization of lone pair or free electrons from one place to another is known as resonance. The stability of compound depends upon the number of resonating structures. More the resonating structures of compound more will its stability.
(c)
Interpretation: A reason for the formation of A rather than hexaphenylethane is to be proposed.
Concept introduction: The
