Concept explainers
Interpretation:
The reason as to why two products are formed in the first ether synthesis, but only one product formed in the second ether synthesis is to be stated.
Concept introduction:
The nucleophilic substitution reactions are the reactions in which one nucleophile is substituted by another nucleophile. These reactions depend upon the nucleophilicity and concentration of the nucleophile. It is of two types,

- (a) Are compounds B–D identical to or an isomer of A? (b) Give the IUPAC name for A.arrow_forwardDraw all constitutional isomeric ethers with the molecular formula C4H10O. Provide a common name and a systematic name for each isomer.arrow_forwardThe following compound has extra stability in its enol form. Explain the reason that may lead to this extra stability and show by drawing the relevant structure. & CH3 CH3arrow_forward
- 6) Classify the following cyclization, part of the mechanism for cyclic acetal formation, according to Baldwin's rules. Harrow_forwardThis ether can be made using a Williamson ether synthesis. The possible bond disconnections are displayed in the structure to the right. Which of the bond disconnections reflects the preferred synthesis of this ether? (The preferred synthesis is the one that produces the ether in higher yields.) A A Either A or B would work equally wellarrow_forwardDraw a stepwise mechanism for the sulfonation of an alkyl benzene such as A to form a substituted benzenesulfonic acid B. Treatment of B with base forms a sodium salt C that can be used as a synthetic detergent to clean away dirt (see Problem 3.22).arrow_forward
- Consider the following reaction and provide the correct IUPAC names for the compounds A and Barrow_forwardDescribe the following chemical reactions as SN1, SN2, E1 and W2. Draw a curved arrow mechanism for each reaction.arrow_forward.. Explain why the all cis isomer of 4-t- butylcyclohexane-1,3-diol forms an acetal with acetone but none of the other isomers do. : You are provided with two bottles labeled "1,2-Cyclopentanediol"; one contains a compound of m.p. 30°C and the other, a compound of m.p. 55°C; both compounds are optically inactive. What simple reaction can you perform on each of them in order to decide which bottle should be labeled "cis" or "trans".arrow_forward
- Explain why tetrahydrofuran has a higher boiling point and is much morewater soluble than furan, even though both compounds are cyclic etherscontaining four carbons.arrow_forwardBromoetherification, the addition of the elements of Br and OR to adouble bond, is a common method for constructing rings containingoxygen atoms. This reaction has been used in the synthesis of thepolyether antibiotic monensin (Problem 18.34). Draw a stepwisemechanism for the following intramolecular bromoetherification reaction.arrow_forwardWhat is the major alkene formed when A is treated with POCl3 andpyridine? Explain why the major product is different in these reactions.arrow_forward
