Concept introduction:
A chemical reaction in organic chemistry which is used for the synthesis of cyclopentenones is known as cyclization reaction.
The nucleophilic substitution reactions are the reactions in which one nucleophile attacks the electrophilic centre and eliminates another group in the compound. These reactions depend upon the nucleophilicity and concentration of the nucleophile.

- How does bromobenzene react differently from benzyl chloride under SN1 and SN2 conditions, and why?arrow_forwardGive the major organic product of the following reaction for a) or b)arrow_forwardEach of the following reactions has been described in the chemical literature and involves an organic reactant somewhat more complex than those we have encountered so far. Nevertheless, on the basis of the topics covered in this chapter, you should be able to write the structure of the principal organic product of each reaction.arrow_forward
- Write down the explicit structures of A, B, C and D in accordance with the reactions given in the synthesis plan, which shows the synthesis of D, a pheromone of moth.arrow_forwardGive the structure of the product and/or intermediates of the following reactions. Indicate, where appropriate, both regiochemistry and stereochemistry.arrow_forwardGive only typing answer with explanation and conclusion What is the main product formed in the Friedel-Crafts alkylation reaction of benzene with 1-butene and AlCl3?arrow_forward
- What happens to the stereochemistry during and SN2 reaction? Why? Provide a reaction to illustrate this.arrow_forwardWhich of the following is statements is/are TRUE about the experiment on the relative rates of electrophilic aromatic substitution?I. The experiment must be performed in dark conditions. II. Using the same solvents, a faster decolorization will be observed in aniline as compared to ethylbenzene. III. Chlorobenzene will react faster than methoxybenzene. IV. The use of AlCl3 in the halogenation of aromatic compounds using elemental bromine could hasten the reaction.arrow_forwardOutline a synthesis of each of the following compounds from isopropyl alcohol. A compound prepared in one part can be used as a reactant in another. (Hint: which of the compounds shown can serve as a starting material to all others?)arrow_forward
- Provide the curved-arrow mechanism to account for the following nucleophilic addition- elimination reaction.arrow_forwardState the effects of substitution on a benzene derivative towards further aromatic substitution. Based on the above suggest the various types of substituents that can be attached to Benzene.arrow_forwardSuggest reactivity of compound A, B and C in increasing order of E2 reactionarrow_forward
