Concept explainers
(a)
Interpretation: The hybridization of carbon atoms of triple bonds is to be predicted.
Concept introduction: Hybridization is the combination of two or more atomic orbitals to form the same number of hybrid orbitals, each having the same shape and energy. Number of groups around the atom is equal to number of the number of orbitals hybridized to give hybrid atomic orbitals.
(b)
Interpretation: The type of orbital in which the pi electrons of the triple bond resides is to be predicted.
Concept introduction: Hybridization is the combination of two or more atomic orbitals to form the same number of hybrid orbitals, each having the same shape and energy. Number of groups around the atom is equal to number of the number of orbitals hybridized to give hybrid atomic orbitals.
(c)
Interpretation: The number of pi electrons that are delocalized in compound A is to be determined.
Concept introduction: A molecule must be cyclic, planar, completely conjugated and should follow
