Question

Read the following questions and answer as per the directions given below:

Statement I: The geometrical isomers of the complex $\left[M\right(N{H}_3{)}_{4}C{l}_2]$ are optically inactive.
Statement II: Both geometical isomers of the complex $\left[M\right(N{H}_3{)}_{4}C{l}_2]$ possess axis of symmetry.
(IIT-JEE, 2008)

• A. Statement I is true; Statement II is also true; Statement II is a correct explanation for Statement-I.
• B. Statement I is true; Statement II is true; Statement II is not the correct explanation for Statement-I.
• C. Statement I is true; Statement II is false.
• D. Statement I is true; Statement II is true.

Answer 1

The correct option is A Statement I is true; Statement II is also true; Statement II is a correct explanation for Statement-I.

The cis and trans forms of the complex $\left[M\right(N{H}_3{)}_{4}C{l}_2]$ are optically inactive. Both geometrical isomers of the complex $M\left(N{H}_3{)}_{4}C{l}_2\right]$ posses axis of symmetry.
