a) Interpretation: Curved arrows are to be added to the polar reaction given to indicate the flow of electrons. Concept introduction: Curved arrows start from a nucleophilic source (neutral or negatively charged) and end in an electrophilic sink (neutral or positively charged). During the flow of the electrons the octet rule must be maintained both in the source and sink. To add: Curved arrows to indicate the flow of electrons in the polar reaction given.

Question

An electrostatic potential map of calicene is shown below. a) Both the electrostatic potential map and its significant dipole moment indicate that calicene is an unusually polar hydrocarbon. Which of the dipolar resonance forms, structure A or structure B, better corresponds to the electron distribution in the molecule? Select the single best answer. b) Which one of the following structures should be stabilized by resonance to a greater extent? Select the single best answer.
