(a)
Interpretation:
Two sets of reagents that might be used to prepare the given Z
Concept Introduction:
Wittig reaction:
Formation of an alkene by the reaction of carbonyl compounds with phosphorus ylide is known as Wittig reaction.
(b)
Interpretation:
The conversion method of Z alkene into disparlure has to be given.
Concept Introduction:
Epoxidation reaction:
Alkenes reacts with peracids and forms
(c)
Interpretation:
The number of possible stereoisomers for disparlure has to be given.
Concept Introduction:
Stereoisomers and chiral:
Isomers differing only in their spatial arrangement of atoms are called as stereoisomers.
The geometric property of a molecule that cannot be superimposed on its mirror image is known as chirality. Chiral carbon is the one which is attached with four different groups or atoms.

- Consider the tetracyclic compound with rings labeled A–D. (a) Which ring is the most reactive in electrophilic aromatic substitution? (b) Which ring is the least reactive in electrophilic aromatic substitution?arrow_forwardCompound W has molecular formula C₁4H18 and reacts with H₂ to form X. Oxidative cleavage of W with O3 followed by CH3 SCH3 affords Y. What is the structure of W?arrow_forwardGive the structure, exclusive of stereochemistry, of the principal organic product formed on reaction of 2,3-dimethyl-1,3-butadiene with each of the following:(a) 2 mol H2, platinum catalyst(b) 1 mol HCl (product of 1,2-addition)(c) 1 mol HCl (product of 1,4-addition)(d) 1 mol Br2 (product of 1,2-addition)(e) 1 mol Br2 (product of 1,4-addition)(f) 2 mol Br2arrow_forward

Hydrogenation of dictyopterene D' with excess H2 in the presence of a Pd catalyst forms butylcycloheptane. Ozonolysis with O3 followed by (CH3)2S forms CH2(CHO)2, HCOCH2CH(CHO)2, and CH3CH2CHO. What are possible structures of dictyopterene D'?arrow_forwardCompound A has molecular formula C7H15B.. Treatment of compound A with sodium ethoxide yields only one elimination product (compound B) and no substitution products. When compound B is treated with dilute sulfuric acid, compound C is obtained, which has molecular formula C7H160. Draw the structures of compounds A, B, and C.arrow_forward
- Q3. 2-Bromopentane, when treated with alcoholic KOH yields a mixture of three alkenes A, B and C. Identify A, B and C. Which is predominant? Q4 Which statement below about Sn1 reactions is incorrect? (A) SN1 reactions are stepwise and have intermediates. (B) The slow step in a SN1 reaction is formation of the carbocation intermediate. (C) SN1 reactions have first order kinetics which means only the alkyl halide is involved in the rate limiting step. (D) The products of a SN1 reaction will be a pair of enantiomers. (E) An aprotic solvent is best for Sn1 reactions as they tend to help stabilize carbocation intermediates.arrow_forwardWrite the structure of the major organic product formed in the reaction of 1-pentene with each of the following: (a) Hydrogen chloride (b) Dilute sulfuric acid (c) Diborane in diglyme, followed by basic hydrogen peroxide (d) Bromine in carbon tetrachloride (e) Bromine in water (f) Peroxyacetic acid (g) Ozone (h) Product of part (g) treated with zinc and water (i) Product of part (g) treated with dimethyl sulfide (CH3)2Sarrow_forward(a) Draw the products (including stereoisomers) formed when 2methylhex-2-ene is treated with HBr in the presence of peroxides.

- The bicyclic heterocycles quinoline and indole undergo electrophilic aromatic substitution to give the products shown. (a) Explain why electrophilic substitution occurs on the ring without the N atom for quinoline, but occurs on the ring with the N atom in indole. (b) Explain why electrophilic substitution occurs more readily at C8 than C7 in quinoline. (c) Explain whyelectrophilic substitution occurs more readily at C3 rather than C2 of indole.arrow_forwardAn organic compound A of unknown structure was found to have a molecular formula C8H16. When A was poured in water and heated, compound B having a molecular formula C8H18O was formed. B upon heating with sulfuric acid was converted to C as the major product which is identical to A. Ozonolysis of C gave one molecule each of two different products D and E, both having a molecular formula C4H8O. Write the reactions involved and determine the structure of A,B,C,D and E.arrow_forward(S)-2-butanol reacts with potassium dichromate (K2CrO4) in aqueous sulfuric acid to give A(C4H3O).
