Predict the products including the stereochemistry of products.
If a racemic mixture is formed, show one of the enantiomers and
write + enantiomers besides the product. If two diastereomers are
formed, show them both.

H3 C H2Br Br2, H30* HC X CH3 HzC CH3 H3C CH3 Aldehydes and ketones can be halogenated at their a-position by reaction with Cl, Br, or 12, under acidic conditions. Using Br2 under acidic conditions, an intermediate enol is formed which adds bromine at the a-position. The reaction stops after the addition of one bromine because the electron-withdrawing halogen decreases the basicity of the carbonyl oxygen, making the protonation less favorable. Not started curved arrows to show the movement...

Q5-Fill in the boxes with the productis), reactantis) or reagent(s) for the following reactions. Draw only the predominate regioisomer and indicate the stereochemistry where appropriate. If a racemic mixture is formed, you may indicate this using a wavy line mor mark the chiral center with an asterisk (), and write racemic in the box. You may also draw both enantiomers and write RACEMIC in the box. Indicate if the product resulted from Sy2, Sn1, E2, E1 in the dotted box...
