- In 1935, J. Bredt, a German chemist, proposed that a bicycloalkene could not have a double bond at a bridgehead carbon unless one of the rings contains at least eight carbons. This is known as Bredt’s rule. Explain why there cannot be a double bond at this position.arrow_forwardDecide whether the following molecule presents an S configuration or R configuration based on the stereogenic carbon.arrow_forwardWhich group in the following pair is assigned the higher priority in R,Snomenclature −CD3, −CH3arrow_forward
- There will be two labeled carbons on the isoprene, one of them is the one at the end of the double bond. Which is the second?arrow_forwardHelp with the following question. Please round the answer to 2 sig figsarrow_forwardConvert the following chair conformation of the sugar beta-D-galactose into a structure that shows all the cis & trans relationships as hashed (down) and wedge (up) bonds. Use the wedge/hash bond tools to indicate stereochemistry where it exists. In cases where there is more than one answer, just draw one. Use “flat” representations of rings, not chairs, in your drawing.arrow_forward
- Consider the structure of tallose below and draw the structures of the following: A. its enantiomer B. an epimer of tallose C. alpha-D tallopyranose D. beta-D tallopyranosearrow_forwardDraw the structure of an achiral tetramethylcyclohexane for which the chair interconversion (chair flipping) results in identical molecules.arrow_forwardStereochemistry in biological molecules is often denoted by the D‑ and L‑ convention, instead of the ?‑ and ?‑ configurations determined by the Cahn–Ingold–Prelog methodology. Naturally occurring α‑amino acids are typically in the L‑configuration. The Fischer projection of L‑alanine is shown. L‑alanine Identify which structures are equivalent to the L‑configuration.arrow_forward
- Stereochemistry in biological molecules is often denoted by the D‑ and L‑ convention, instead of the ?‑R‑ and ?‑S‑ configurations determined by the Cahn–Ingold–Prelog methodology. Historically, the glyceraldehyde enantiomer that rotated plane polarized light clockwise was arbitrarily designated as D and the other enantiomer was designated as the L configuration. The D‑glyceraldehyde Fischer projection is shown. D‑glyceraldehydearrow_forward1.Build a carbon chain of 9 carbon atoms, which has an alkene, an alcohol, an amine.
