Neither optical nor geometrical isomers can be distinguished by mass spectroscopy. Why
(ii) Select the pairs of
(a) Geometrical isomers,(b) Optical isomers
( c ) Identical structures




(III) Which one of followig will show optical activity
Identifly the type of insomerisum in (if no isomerism then indicate none

Explanation

Since all atoms in each isomers are attached to the same other types of atoms the same fragments are expected when the molecules are split Therefore ultraviolet (UV) nuclear magnetic resonance `(NMR)` and `X` ray diffraction conductance method electrolysis method chemical method dipole magnetic and magnetic properties menthod are used to distinguish isomers
(II) a Geometrical isomers are 1 and 3 4 with 6 and 8
(b) Optical isomers are 6 and 8
(c) Identical stures are 1and 2, 4, 5 and 7
(III) Optical active isomers are 2 and 3 Optical inactive isomers are
(i) I it is trans and has mirror plane i. e, plane of symmetry thrugh (en) groups
(ii) 5,it has plane of symmetry through the two CI atoms
(iii) 4 it has centre of symmetry
(iv A) Geometrical isomers
(B) None (C) None (D) None (E) Optical active isomers .
