Answer to Question #218094 in Inorganic Chemistry for Mohammed Ariful Is

Question

 Hydroboration of styrene followed by oxidation with hydrogen peroxide leads to the formation of compound A. Oxidation of styrene with potassium permanganate in an acidic medium results in compound B. Compounds A and B can react with each other under acidic catalysis to form compound C. 

What is the volume of carbon dioxide (molar volume of ideal gas Vm = 22.4 L/mol), released during the complete combustion (in excess of O2) of 5.00 grams of compound C?

a) 7.00 L

b) 7.43 L

c) 7.67 L

d) 8.02 L

e) 8.31 L

Answer 1

Hydroboration-Oxidation is a two step pathway used to produce alcohols. The reaction proceeds in an Anti-Markovnikov manner, where the hydrogen (from BH3 or BHR2) attaches to the more substituted carbon and the boron attaches to the least substituted carbon in the alkene bouble bond.
