(a) Interpretation: The conversion of ball-and-stick model to a skeletal structure that clearly shows the stereochemistry at the ring fusion of given decalin derivative is to be stated. Concept introduction: Decalin and its derivatives involve fusion of two six-membered rings that share a C − C bond. The substituents present at ring fusion are identified as cis or trans. If substituents present at ring fusion are present opposite sides to each other, then it is identified as trans, and if substituents present at ring fusion are present same sides to each other, then it is identified as cis.

Question

Draw the products formed when each alkene is treated with BH3 followed by H2O2,HO−. Include the stereochemistry at all stereogenic centers.
