Statement I : The geometrical isomer of the complex [M(NH3)4Cl2] are optically inactive.

Question

Read the following questions and answer as per the direction given below 

(a) Statement I is true; Statement Ii is true; Statement II is a correct explanation of Statement I. 

(b) Statement I is true; Statement II is true; Statement II is not the correct explanation of Statement I.

(c) Statement I is true; Statement II is false. 

(d) Statement I is false; Statement II is true.

Statement I : The geometrical isomer of the complex [M(NH₃)₄Cl₂] are optically inactive. 

Statement II : Both geometrical isomers of the complex [M(NH₃)₄Cl₂] possess axis of symmetry.

Answer 1

The correct option (a) Statement I is true; Statement Ii is true; Statement II is a correct explanation of Statement I. 

Explanation:

The cis and trans both form of complex [M(NH₃)₄Cl₂] are optically inactive.

There are plane of symmetry in addition to that there is alternate axis of symmetry (C_n) which also causes their optical inactivity.
