Question

An optically active alkene (I) with lowest molecular mass on hydrogenation gives optically inactive alkane, but on insertion of methylene carbene $(:C{H}_2)$ in (I), it gives optically active compound (II). The compounds (I) and (II) are:

• A. P
• B. P, R
• C. P, Q
• D. P, Q, R
• E. All

Answer 1

The correct option is C P, Q

An optically active alkene (I) with lowest molecular mass on hydrogenation gives optically inactive alkane, but on insertion of methylene carbene $(:C{H}_2)$ in (I), it gives optically active compound (II). The compounds (I) and (II) are P, Q.
as in P and Q, both (I) and (II) are optically active.
