Concept explainers
(a)
Interpretation: The curved arrow to show electron movement in the first carbocation rearrangement should be drawn.
Concept introduction: Carbocation is a general term employed for a postively charged carbon irrespective of valency of carbon. In carbocation, carbon is bonded to 3 atoms or groups and has only sextet of electrons so it behaves as an electron-deficient species. It is
The order of relative stability of various possible carbocation species is as follows:
Some special carbocation may attain stability via ring explosion. This also occurs since five-membered rings are more stable than strained three or four-membered ring.
(b)
Interpretation: The curved arrow to show electron movement in the second carbocation rearrangement should be drawn.

(c)
Interpretation: The force that drives this rearrangement should be illustrated.

Label each orbital as bonding, antibonding, or non-bonding. c. Label the HOMO and LUMO where appropriate. d. Designate whether the molecule will react more readily with a nucleophile or an electrophile and designate which atom or atoms it will react most readily with using evidence from the molecular orbital diagram.arrow_forwardDraw both resonance structures of the most stable carbonation intermediate in the reaction shown belowarrow_forward
- Complete the reaction in the drawing area below by adding the major products to the right-hand side. If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead. Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds. Just draw one molecule to represent each pair of enantiomers, using line bonds at the chiral center. More... i x + P C 1. NaOMe Click and drag to start drawing a structure. 2.
