Please Solve these with step by step instructions with phases. It is very hard to understand how to solve them without a photograph and an explanation of why you chose each step. Plant the following reactions showing a mechanism for the following transformations. A.) 3-Hexyne into Meso-3,4dihydroxyhexane B.) Cis,trans 2,4 hexadiene AND 1,2 dicyanoethylene into symmetric sterioisomers of 4,5dibromo-1,2dicyano-3,6 dimethylcyclohexane
