Concept explainers
Interpretation: Reason for greater stabilty of benzylic carbocation than allylic carbocation should be determined.
Concept introduction: Organic compounds are covalent in nature that undergoes a reaction by heterolytic cleavage or homolytic cleavage.
In heterolytic cleavage, shared pair of electrons is taken away by one of the atoms which result in charged species. In homolytic cleavage, shared pair of electrons are equally distributed between two atom that results in free radicals.
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

Organic Chemistry: A Guided Inquiry
- What are Allylic Carbocations ?arrow_forwardA benzene ring alters the reactivity of a neighboring group in the so-called “benzylic” position, similarly to how a double bond alters the reactivity of groups in the “allylic” position. Benzylic cations, anions, and radicals are all more stable than simple alkyl intermediates. a) Use resonance structures to show the delocalization of the positive charge, negative charge, and unpaired electron of the benzyl cation, anion, and radical.arrow_forwardDraw the alkene that would react with the reagent given to account for the product formed. ? + + H₂O **** H₂S04 • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just draw one.

- Explain about the Stability of alkenes ?arrow_forwardOrganic Chemistry Acid catalyzed dehydration reaction of 2-methyl-1-butanol produces 2-methyl-2-butene as the major product. Also acid catalyzed dehydration reaction of 3-methyl-1-butanol give the same product as major product. Explain the reason why both of the reaction produce the same product as the major product.arrow_forwardDraw the alkene that would react with the reagent given to account for the product formed.

- Explain the characteristics of electrophilic addition of HX to alkenes ?arrow_forwardThe following compounds have the same molecular formula as benzene. How many monobrominated products could each form? a. How many dibrominated products could each of the preceding compounds form? (Do not include stereoisomers.) b. How many dibrominated products could each of the compounds form if stereoisomers are included?arrow_forwardDraw the alkene that would react with the reagent given to account for the product formed. ? + HCI CH3 CH3CCH3 CI • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • In cases where there is more than one answer, just draw one. #[ ] در ChemDoodlearrow_forward
