Concept explainers
Interpretation:
According to the terpene rule, the structure of caryophyllene needs to be explained.
Concept introduction:
Terpene rule or isoprene rule states that terpenoids structures are obtained by linking isoprene unit. Isoprene (2-methyl-1, 3-butadiene) is the monomer of natural rubber.
Answer to Problem 3Q
The structure of caryophyllene fits in the terpene rule as caryophyllene contains a moiety which is similar to the polyisoprene unit.
Explanation of Solution
The structure of caryophyllene is represented as follows:
The
Polymerization of isoprene leads to a basic structure that is present in all terpenoids (shown in red). Similarly, caryophyllene also has a similar moiety (shown red) as present in terpenoids. Thus, the structure of caryophyllene fits in the terpene rule.

- Assuming you are a chemist and you need to extract ethanolic acid in a benzene solution. Propose and briefly discuss how to extract the ethanolic acid in the benzene solution. Include the reactions involved in each step, if any.arrow_forwardImagine that phenol (“hydroxybenzene”) and nitrobenzene are reacted (in separate beakers) with a hot solution containing both concentrated sulfuric acid and concentrated nitric acid. A) In analyzing the products, you discover that the substitution pattern resulting from the reaction with phenol differs from the reaction with nitrobenzene. Explain this difference in substitution patterns using one or more judiciously selected reaction mechanisms or portions of mechanisms.arrow_forwardOrganic chemistry:Discuss the Grignard synthesis of triphenyl methanol and benzoic acid .arrow_forward

Carboxylic acid and their derivatives readily react with alcohols. (i) Name the reaction and give the generic name of the product of such a reaction. (ii) The reaction of salicylic acid with acetic anhydride is an example of such a reaction as in (i) above. Show the mechanism of the reaction.

Now suppose you add in aqueous sodium bicarbonate and vigorusly shake the contents of the separatory funnel. ethanol will be dissolved in tert butyl methyl ether ether and valeric acid will be dissolved in the aqueous sodium bicarbonate layer. Draw the EXACT chemical structure that will exist in each of the layers after shaking with sodium bicarbonate. (Is it neutral or charged?)arrow_forwardIn this study, the researcher compared S N 2 and E2reaction rates for four substrates. Three of the substrates had a second halogen on the bposition in the molecule. This work also compared the behavior of two nucleophiles:dianion I and II. You should read the abstract and look at Scheme 1 (p. 3082) and Table 4(p. 3086). Abstract: The gas-phase reactions of benzoate and phenolate containing dianions with a series of ‚-substitutedalkyl bromides (X-CH2CH2Br, X ) H, F, Cl, Br) have been studied in a quadrupole ion trap mass spectrometer.Branching ratios between SN 2 and E2 products were measured and rate constants were determined. The‚-halogens increase both the S N 2 and E2 rates, but the effect is greater for the latter process and thereforethese substituents lead to an increase in the amount of elimination. The kinetic data for the SN 2 reactions canbe analyzed via a two-parameter, linear free-energy relationship and the results indicate that field-effects (i.e.,electron-withdrawing…arrow_forward
