Question

Choose the correct set of options matching appropriate properties of column-I with column-II

• A. (c) – (p, s); (d) – (q, r)
• B. (c) – (r); (d) – (t)
• C. (c) – (q, r, t); (d) – (q, s, t)
• D. (c) – (r, t); (d) – (p, s)

Answer 1

The correct option is A (c) – (p, s); (d) – (q, r)


This molecule has one stereogenic centre in the form of double bond with each of the carbons having only one group in common. The other stereogenic or chiral centre is at the deuterated carbon which has 4 different groups.


This molecule is optically inactive despite having 2 stereogenic centres due to the presence of a plane of symmetry.


This is a chiral species which is optically active.

This molecule does not show optical activity due to presence of a plane of symmetry.
