Question

Which of the following complexes will show optical isomerism?

• A. $\left[Cr\right(N{H}_3{)}_6{]}^{2+}$
• B. $\left[Ni\right(H_{2}O{)}_6{]}^{2+}$
• C. $\left[Pt\right(N{H}_3{)}_{3}Br]N{O}_3$
• D. $\left[Cr\right(en{)}_3]C{l}_3$

Answer 1

The correct option is D $\left[Cr\right(en{)}_3]C{l}_3$

As it does not contain plane of symmetry and centre of symmetry and centre of symmetry ,so it is optically active (chiral)compound.
