Please help! I only have one more chance to draw this correctly! Draw the starting alcohol that would react with PBrз to form the alkylbromide shown below in the 3D ball-and-stick representation.Stereochemistry is graded. In the representation, a gray ball indicates acarbon atom, a white ball indicates a hydrogen atom and a brown ballindicates a bromine atom.Incorrect, 1 attempt remainingHHHHHO☑HHHHHHHSelect to Draw Starting AlcoholIncorrect, 1 attempt remainingThe relative orientation of a stereocenter(s) (chiral center(s)) is notproperly shown.

A sulfonium ion (R3S+) is a stereogenic center if three different alkyl groups are bonded to sulfur because sulfur is surrounded by four different groups, including its lone pair. In assigning an R or S) is a stereogenic center if three different alkyl groups are bonded to sulfur because sulfur is surrounded by four different groups, including its lone pair. In assigning an designation to sulfur, the lone pair is always assigned the lowest priority (4). SAM, S -adenosylmethionine, is a biologically active sulfonium ion that we will learn about in Section 7.16. Locate all the stereogenic centers in SAM, and assign an R,S designation to each center.
