Interpretation: The conversion of ball-and-stick model to a skeletal structure that clearly shows the stereochemistry at the ring fusion of given decalin derivative is to be stated.
Concept introduction: Decalin and its derivatives involve fusion of two six-membered rings that share a

- A key step in the synthesis of β-vetivone, a major constituent of vetiver, a perennial grass found in tropical and subtropical regions of the world, involved the reaction of compound A and dihalide B with two equivalents of LDA to form C. Draw a stepwise mechanism for this reaction. β-Vetivone contains a spiro ring system—that is, two rings that share a single carbon atom.arrow_forwardRank the attached isomers in order of increasing boiling point.arrow_forwardExplain why tetrahydrofuran has a higher boiling point and is much morewater soluble than furan, even though both compounds are cyclic etherscontaining four carbons.arrow_forward
- A is a toxin produced by the poisonous seaweed Chlorodesmis fastigiata. (a) Label each alkene that exhibits stereoisomerism as E or Z.arrow_forward(A) Which is the anti-conformer of hexane in Newman projection? (B) Which is the equivalent structure of LAM in sawhorse representation? (C) Which is the most stable conformation of pentane in Newman projection?arrow_forwardIn which chair conformation (a or b) is the methyl group farthest from the neighboring hydrogen atom? In which chair conformation (a or b) does the methyl group have greater room? Which is the preferred conformation of methylcyclohexane (a or b)?arrow_forward
- Answer each question using the ball-and-stick model of compound A. Draw a constitutional isomer that contains an ether and give its IUPACname. Draw the products formed (including stereochemistry) when A istreated with each reagent: [1] NaH; [2] H2SO4; [3] POCl3, pyridine; [4]HCl; [5] SOCl2, pyridine; [6] TsCl, pyridinearrow_forwardWhich compounds (B–F) are identical to A? (b) Which compounds (B–F) represent an isomer of A?arrow_forwardIsomers with the same boiling point and molecular weight but have different boiling points how is this possible ?arrow_forward
