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.

- To satisfy the octet rule, fullerenes must have doublebonds. How many? Give a simple rule for one way ofplacing them in the structure shown in Figure 7.17a.arrow_forwardAmong the four alkanes, ethane, propane, butane, and pentane, which is capable of existing in isomeric forms?arrow_forwardExplain the inductive effect in organic chemistry by using the example of diketones.arrow_forward
- For the four classes of hydrocarbons (Alkane, Alkene, Alkyne, Arene): Give a structural formula example of each, or identify the characteristic bond that is present.arrow_forwardAnswer true or false to the following statements about energy diagrams and reactions. Q.) Thermodynamics is the study of the energies of structures that are represented by wells on reaction coordinate diagramsarrow_forwardPolymers are given below in image, give monomer units for all these in clear handwritten.arrow_forward
- Define Amalgamsarrow_forwardFor which isomer would you expect a greater equilibrium percentage of molecules with the alkyl group in the axial position, explain.arrow_forwardSince the heat of reaction is negative, why isn't the heat of reaction negative for octane, too? Is it because the heat of reaction for octane is before the reaction takes place, and hence before the release of heat? Is this the reason why octane's heat is positive, while the reaction as a whole is negative? Because it must have to do with the conservation of energy. Perhaps the reaction is the system, and octane is part of the surroundings, hence the opposite signs?arrow_forward
