Concept explainers
Interpretation:
An energy diagram for the three molecular orbitals of the cyclopropenyl system is to be drawn. How these three molecular orbitals are occupied in the cyclopropenyl anion, cation and radical is to be indicated. Which among the three is
Concept introduction:
The numberof molecular orbitals formed is equal to the number of orbitals overlapping. The available orbitals are filled by the electrons in the increasing order of their energies.Each moleclar orbital can accommodate two electrons with opposite spin. Electrons occupy the orbitals individually first before they get paired in the same orbital.
The cyclopropenyl cation has two electrons to be filled in molecular orbitals.
The cyclopropenyl radical has three electrons to be filled in molecular orbitals.
The cycloproenyl anion has four electrons to be filled in molecular orbitals.
To draw:
The relative energy levels of the three π molecular orbitals of the cyclopropenyl cation, radical and anion.
To indicate:
How the three π molecular orbitals are filled in cyclopropenyl cation, radical and anion.
To state:
Which of these three are aromatic.

Bond enthalpies are CH : 412 kJ/mol; CC : 348 kJ/mol;CC : 612 kJ/mol; CBr : 276 kJ/mol;BrBr : 193 kJ/mol. 1.317 kJ/mol 2.507 kJ/mol 3.95 kJ/mol 4.288 kJ/mol 5.181 kJ/molarrow_forwardThe unsaturation number or degree of unsaturation (U) can be used to determine the number of rings and multiple bonds in a compound from its molecular formula. Given a structure, you can determine the number of hydrogens without having to count them explicitly. Consider three compounds and their degree of unsaturation. (a) A compound A has the molecular formula C7H13ClN2OC7H13ClN2O. How many rings and/or π bonds does it contain?arrow_forward

Antiaromatic compounds have at least one sp³ hybridized atom in the ring. Antiaromatic compounds are not conjugated. Only aromatic compounds have 4n+ 2 pi electrons. The structure must be cyclic for aromatic but not antiaromatic compounds. Aromatic, not Antiaromatic compounds, are planar.arrow_forwardThe bond lengths of ethane, ethene, and ethyne were determined, and a graph of the C-H bond length vs. % s-character of the C hybrid orbital was made.
