Interpretation:
Structural formula for the major product for alkyl bromide, when each of the given alcohols is reacted with hydrogen bromide, is to be drawn using the same format for alkyl bromide as the original given alcohol. IUPAC name for each alkyl bromide including its stereochemistry is to be given.
Concept introduction:
Secondary and tertiary alcohols react with hydrogen halides by the
Primary alcohols and methanol react with hydrogen halides by the
There is a possibility of a formation of a racemic mixture to give a mixture of stereoisomers when optically active alcohols react with hydrogen halides in an
There is an inversion of configuration for the reaction of optically active alcohols with hydrogen halides in an
The three dimensional spatial arrangement of substituents at a chirality center is called the absolute configuration.
The Cahn-Ingold-Prelog rule system ranks the substituents in the chirality center in the order of decreasing
In next step, molecule is oriented such that the bond to the lowest ranked substituent points away from the observer. Then check the path of sequence of decreasing priority. If the path of sequence of decreasing priority is clockwise then the configuration is R and if path of sequence of decreasing priority is anticlockwise, then the confirmation is S.

- Determine the configuration of each stereogenic center in the compound below. Highlight the carbon in red if the configuration is R, and in blue if the configuration is S.arrow_forwardUsing the Cahn–Ingold–Prelog sequence rules, assign priorities to the groups around the chiral carbon in carvone. Draw the structural formulas for (+)- and (-)-carvone with the molecules oriented in the correct position to show the R and S configurations.arrow_forwardConsider a solvatochromic compound that is blue in water and orange in acetone. Which of the following statements about this compound is true? Group of answer choices The compound exhibits positive solvatochromism The compound exhibits negative solvatochromism In ethanol - a solvent with a polarity between those of water and acetone - the compound would be yellow in color The HOMO is more stabilized by polar solvents than the LUMOarrow_forward
- Convert each ball-and-stick model to a skeletal structure that clearlyshows the stereochemistry at the ring fusion of these decalin derivatives.arrow_forwardWrite the IUPAC name of the following molecule: *Lowercase letters only and DONOT put space in between. DO NOT include stereochemistry. (kindly show explanation or illustration. thank you!)arrow_forwardGive the IUPAC name for the following compound. Be sure to indicate stereochemistry where necessary.arrow_forward
- Alkenes can be converted to alcohols by hydroboration–oxidation. Draw the structure of the alcohol(s) formed in the following reaction sequence. If applicable, draw hydrogen at a chirality center and use wedge-and-dash bonds to designate the stereochemistry.arrow_forwardGive the systematic (IUPAC) name for the following compounds. Include stereochemistry in the name ONLY FOR THOSE STRUCTURES THAT ALLOW YOU TO DETERMINE STEREOCHEMISTRY. In other words, describe the stereochemistry if the molecule is shown as a Fisher projection, or as a perspective formula, or if an alkene is drawn with the correct stereochemistry representation.arrow_forwardPlease advise if these models resemble the cis-2-bromocyclohexanol & trans-2-bromocyclohexanol. Can you please advise on the priority numbers of each substituent. I am confused from the reading. Is the proproty a single element, the group of elements, the left and right carbon atoms? Please advise and give commentary on Br. & Methyl group oriantation related to the doubl carbon bond plain. And if you can provide a visual that would be even better for the futre, the more detail the better my study notes will be. Thank you. Justinarrow_forward
- What are the IUPAC's for each structure?arrow_forwardWrite the IUPAC name of the following molecule: *Lowercase letters only and DO NOT put space in between. If there is a complex substituent, name it SYSTEMATICALLY. Do not use special names. DO NOT include stereochemistry.arrow_forwardConsider the molecule: rate the priority functional groups from highest to lowest A. Alkyl chain B. Ketone C. Carbonyl D. Anhydridearrow_forward
