QJEEAdv08Che40f: JEE Advanced 2008 Chemistry - Class 12 JEEAdv08Che40f Solution: Statement 1 : The geometrical isomers of the complex [M(NH ) Cl …

Statement 1 : The geometrical isomers of the complex [M(NH 3_3 ) 4_4 Cl 2_2 ] are optically inactive.

Statement 2 : Both geometrical isomers of the complex [M(NH 3_3 ) 4_4 Cl 2_2 ] possess axis of symmetry.

Multiple Choice Options

  • A Statement 1 is True, Statement 2 is True; Statement 2 is a CORRECT explanation for Statement 1.
  • B Statement 1 is True, Statement 2 is True; Statement 2 is a NOT CORRECT explanation for Statement 1.
  • C Statement 1 is True, Statement 2 is False.
  • D Statement 1 is False, Statement 2 is True.

Step-by-Step Verified Solution

For a complex to be optically active, it should not possess either centre of symmetry or axis of symmetry or plane of symmetry. Here, the given complex is an octahedral complex that possesses plane of symmetry as well as axis of symmetry and thus is optically inactive.

The ciscis and transtrans both form of complex [M(NH 3_3 ) 4_4 Cl 2_2 ] are optically inactive.
