Question

10.Write short notes:(10)a)Photoelectric effectb)Gerade and Ungeradec)Degenerate orbitalsd)Enantiomersc)Chromophores

Answer 1

photoelectric effect or photoemission is emission of electrons or other free charge catteries when light is shoot on a material.
.
.
others are called ungerade if inversion through centre of symmetry in a molecule result in the same phase for the molecular orbital then mo.. said to have gerade symmetry.
.
.
electron orbitals that have same energy is called as degenerate orbitals.
.
.
optical isomers is one of two stereo isomers that are mirror image of each other that are not superposable.
.
.
atom or group whose presence is responsible for the colour of a compound......
