Question about 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?
How much energy would be required to melt 74 g of HCl at its melting point of -110.8 ? C? ?Hfus for HCl is 14.2 cal/g and ?Hvap for HCl is 98.7 cal/g. Answer in units of cal.
