Determine which one of the labeled atoms is a chiral
center.
If there is no chiral center, answer "none". _____
How many stereoisomers do you expect ?
b atom is the chiral center. No of stereoisomers = 2n n= no of chiral centers. Therefore no of stereoisomers = 21
Possible stereoisomers = 2.

1 & 2) Draw the product to the reaction below. 3) Select the chiral atoms in the aspartame molecule. Draw the product to the reaction below: + OH CH3 H3C—_—HĆ-CH3 + H3C—CH2-OH 6-CH2-CH3 + H20 Draw the product to the reaction below: H3C-CH2-0 H3C—CH2—C—OH + CH3 H3C—CH2-OH + H20 Aspartame is a popular sugar substitute. It is 150 times sweeter than sucrose so very little is needed to sweeten foods. Identify the chirality center(s), sometimes called chiral carbon atoms, in...

CH3CHCH2CHCH; CH3 number of chiral carbon atoms 2 number of total possible stereoisomers 4 OH O c. HOCH CHCHÖCH,OH OH number of chiral carbon atoms number of total possible stereoisomers
In this problem, how do you know which atoms or groups are going away, towards you, or in plane from the chiral center? for example, why do they assume that hydrogen is going away (dotted line) and Ch3 is coming towards you (bold colored line)? And how do you know which direction Ch2Ch2Br and Br is going in? its just a single line (Not dotted or bold). I know directions are important in determining R/S. Ex: In the second photo...
