The oxidation number of bromine in KBr is to be determined. Concept introduction: Oxidation of a species involves the loss of electrons by that species and reduction of a species involves the gain of electrons by that species. The oxidation number is defined as the formal charge an atom would gain if all the bonds attached to it in a compound are heterolytically cleaved. Oxidation number can be a positive or negative number but cannot be fractional.

Write structural formulas for the major products by
doing addition reactions
1. You must add H2 as Pt is catalyst it does not take part in reactions
only speed up the process
H₂
CH2=CH-CH3
Pt
2. Add HCI break it into H and Cl
CH3
HCI
3. Add Br2 only CC14 is catalyst
CH3-CH=CH2
B12
CCl4
4. Add water to this and draw major product, H2SO4 is catalyst you have add
water H20 in both the reaction below
H₂SO4
CH3-CH=CH2
CH3
H2SO4/H₂O
CH3-C=CH2

Plan the synthesis of the following compound using the starting
material provided and any other reagents needed as long as
carbon based reagents have 3 carbons or less. Either the
retrosynthesis or the forward synthesis (mechanisms are not
required but will be graded if provided) will be accepted if all
necessary reagents and intermediates are shown (solvents and
temperature requirements are not needed unless specifically
involved in the reaction, i.e. DMSO in the Swern oxidation or
heat in the KMnO4 oxidation).
