Concept explainers
(a)
Interpretation:
The aromatic cyclopolyenes with a single positive charge are to be predicted.
Concept introduction:
The movement of delocalized pi electrons leads to the corresponding resonance structures. The stability of a compound depends upon the number of resonating structures. The compounds which follow the
(b)
Interpretation:
The aromatic cyclopolyenes with double positive charge are to be predicted.
Concept introduction:
The movement of delocalized pi electrons leads to the corresponding resonance structures. The stability of a compound depends upon the number of resonating structures. The compounds which follow the Huckel rule of aromaticity are known as aromatic compound.

- A laser emits a line at 632.8 nm. If the cavity is 12 cm long, how many modes oscillate in the cavity? How long does it take for the radiation to travel the entire cavity? What is the frequency difference between 2 consecutive modes?(refractive index of the medium n = 1).arrow_forwardA laser emits a line at 632.8 nm.

- For the single step reaction: A + B → 2C + 25 kJ If the activation energy for this reaction is 35.8 kJ, sketch an energy vs. reaction coordinate diagram for this reaction. Be sure to label the following on your diagram: each of the axes, reactant compounds and product compounds, enthalpy of reaction, activation energy of the forward reaction with the correct value, activation energy of the backwards reaction with the correct value and the transition state. In the same sketch you drew, after the addition of a homogeneous catalyst, show how it would change the graph. Label any new line "catalyst" and label any new activation energy.arrow_forwardHow many grams of C are combined with 3.75 ✕ 1023 atoms of H in the compound C5H12?arrow_forwarde. f.
