Question

Select optically active complex.

A)- Only IV
B)- I and IV
C)- I,II and III
D)- I and III

Answer 1

Hint : Optical activity refers as to if or not a compound has optical isomers. A coordinate compound that's optically active has optical isomers and a coordinate compound that's not optically active doesn't have optical isomers. Optical isomers don't exhibit symmetry and don't have identical mirror images.

Complete Step By Step Answer:
A chiral molecule that rotates light is claimed to be optically active. If the molecule rotates the plane-polarized light within the clockwise direction, we call that rotation a dextrorotatory rotation. However, if the sunshine rotates counterclockwise, we call that rotation levorotatory.
Optical isomers are compounds that are nonsuperimposable mirror images of every other. ... If the arrangement in space makes the 2 isomers nonsuperimposable mirror images of every other, we call them optical isomers or enantiomers. An example is the amino alkanoic acid alanine.
An Optically active complex is (iii) also as all substituents are different from chirol.
Hence option A is the correct answer.

Note :
Optically active compounds are those which may rotate the plane of plane polarised light, and people which do not are Optically inactive compounds. Two compounds with an equivalent brute formula are called isomers.
