Concept explainers
(a)
Interpretation:
Rings of the cholesterol steroid have to be labeled.
Concept Introduction:
Group of lipids that consist of 1 five-membered ring and 3 six-membered rings in its skeleton structure are called steroids. Steroids differ with each other in terms of the attachment of the substituent and thus this changes their identity. The skeleton structure of steroid is as follows:
(b)
Interpretation:
Carbon number to that
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
Location of double bond in cholesterol has to be determined.
Concept Introduction:
Refer to part (a).
(d)
Interpretation:
Polar bonds in cholesterol and insolubility of cholesterol in water have to be explained.
Concept Introduction:
Refer to part (a).

- man Campus Depa (a) Draw the three products (constitutional isomers) obtained when 2-methyl-3-hexene reacts with water and a trace of H2SO4. Hint: one product forms as the result of a 1,2-hydride shift. (1.5 pts) This is the acid-catalyzed alkene hydration reaction.arrow_forwardNonearrow_forward. • • Use retrosynthesis to design a synthesis Br OHarrow_forward
- 12. Choose the best diene and dienophile pair that would react the fastest. CN CN CO₂Et -CO₂Et .CO₂Et H3CO CO₂Et A B C D E Farrow_forward(6 pts - 2 pts each part) Although we focused our discussion on hydrogen light emission, all elements have distinctive emission spectra. Sodium (Na) is famous for its spectrum being dominated by two yellow emission lines at 589.0 and 589.6 nm, respectively. These lines result from electrons relaxing to the 3s subshell. a. What is the photon energy (in J) for one of these emission lines? Show your work. b. To what electronic transition in hydrogen is this photon energy closest to? Justify your answer-you shouldn't need to do numerical calculations. c. Consider the 3s subshell energy for Na - use 0 eV as the reference point for n=∞. What is the energy of the subshell that the electron relaxes from? Choose the same emission line that you did for part (a) and show your work.arrow_forwardNonearrow_forward
