help please #1

When 5-hexen-3-one is reacted with slightly less H2 than substrate, along with Pt, Pd or Ni metal, the major substrate product will contain the following functional groups: alkene & alcohol. alkene & ketone, since no reaction occurs under these conditions. alkene only. ketone only. alcohol only.

iii.Draw the structures of the major organic product(s) or condition(s) denoted by A to E in the following reactions. Show stereochemistry of products, if any. OH Br base (e.g. NaH or NaOH) C

Draw the products for the following reactions, assume the reagents are in excess unless other equivalents are listed. Clearly indicate the stereochemistry where important
