Homework Answers
The structure of a compound, that is, a cation is given. To draw the resonance structure of the given compound, delocalize the 
electrons. The curved arrow shows the direction of movement of electrons towards the electron deficient species or towards the more electronegative atom.
Resonance structure can be drawn by the delocalization of 
electron present in a conjugated system, that is, a system in which alternate double and single bonds are present.
The delocalization of electron in a molecule lowers the resonance energy and thus, the molecule is stabilized. Consider the following example for drawing the resonance structure:
Part (a)
Draw the resonance structure of the given compound as shown below:
Therefore, the resonance structure of the given cation is B and C.
Part (b)
The curved arrow representation is as follows:
The resonance structures of the given compound are as follows:
The curved arrow representation that shows the formation of different resonance structure is as shown below:
