2. For each of the following molecules, determine which are chiral and hich are achiral, and write the appropriate word in the box provided. Then, for each that is chiral draw the mirror image and determine RIS configuration to every stereogenic center within the mirror image you drew. (a) Chiral or achiral? OH CH3 (b) (c) NH2 H2N. CH3 CH3 H (d)

How to complete A?

For each of the following molecules, assign whether the molecule is chiral or achiral

Consider (2R,3R)-2,3-dioidobutane: (a)Draw a Fischer Projection of this structure with C1 on top and C4 on bottom. (b)Draw a Newman Projection of of the meso compound of 2,3-dibromobutane looking down the C2-C3 bondwith C2 in front, and label your asymmetric carbons as S or R.

Q2. Identify each of the following molecule as chiral or achiral. (By circling the chiral ones.) Write “meso" where it applies. (In other words, if it is achiral despite having chiral centers). н он NH2 H CH3 Но H3CƠ H H3CO H H HO" н он OH H CH3 H3C H

The S isomer of 2-chlorobutame (below) can react with chlorine to make 5 isomers of dichlorobutane. Draw a Fisher projection each isomer, label all of the chiral centers as R or S, and designate the enantiomer and diastereomer relationships. (This is a reaction you have never seen before, it is capable of removing any hydrogen in the molecule and replacing it with a chlorine. It is a 2,step reaction with a free radical intermediate) CH, -CI + Н-с-н Ch C4H3 Ch + HCI CH,

Please explain the steps and reasoning

CH3.. -Br CH;CH2 mirror plane Draw the Fisher projection of the R enantiomer of 2-bromobutane below 3. the R enantiomer of 2-bromobutane. Retain the model you made of the S initials Secure the initials of your TA after showing them your physical model of 4. enantiomer intact on the side. 23 ch are of the mode of the chiral carhe .Is you drew be
