Give the structure of an optically active alkene `(A)` having the lowest molecular mass, which on catalytic hydrogenation gives an optically inactive compound `(B)`.

Give the structure of an optically active alkyne (A) having the lowest molecular mass, which on hydrogenation with Lindlard's catalyst and Birch reduction gives the same lowest molecular mass optically active alkene.

Give the structure of an optically active alkyne (A) having the lowest molecular mass, which on hydrogenatio with Lindlar's catalyst and Birch reduction gives the same lowest molecular mass optically active alkene. Also explain why. ltbr. But alkyne (A) on hydrogenation with D2 , with Lindlar's catalyst, and reduction with Na+ liq. ND_(3)+EtOH gives a different optically active alkene. Explain.

Give the structure of an optically active hydrocarbon ( C_6 H_12 ) which on catalytic hydrogenation gives an optically inactive compound ( C_6 H_14 )

Which of the following is an optically inactive compound?

The optically active alkane of lowest molecular mass which is also chiral is-

C(C_(6)H_(12)) , and optically active dydrocarbon which on catalytic hydrogenation gives an optically inactive compound, C_(6)H_(14) .
