Hydroboration reaction

In an experiment that is performed you use 1-hexene and is reacted with H2SO4 with water as the solvent. The product formed is 2-hexanol, is this an example of 1,4 addition, or proceeds via a carbanion, or is an example of electrophillic addition, or results in sp2 hybridized carbon being transformed into a sp hybridized carbon ...continues

Hydroboration reaction

In one experiment you combine 1-hexene which is reacted with H2SO4 with water as the solvent and the compound produced is 2-hexanol, and in another experiment you have 1-Methylcyclohexene which reacts with H2SO4 in water to produce 1-methylcyclohexanol. Do the reactions in these experiments conform to E2 elimination, Markovniko ...continues
