Homework Answers
Enantiomers are optically active isomers, which are non superimposable mirror images. They differ in the way they affect plane polar polarized light.
Also they show similar chemical reaction, but they dow different biologcal activity.
Hence option B and Option D is correct option.
Chemical property - Biological activity
physical property- optical activity

Many of the water properties lead to some crucial physical, chemical and biochemical processes that are closely related to environmental and health problems. Some people state: (I) A relatively high dissolution of O2 in water is due largely to the dipolar property of water molecules. (II) Although the density of water changes only slightly with temperature, its change can cause lake water turnover or stratification. (III) Since water dissociation is so small (H2O รณ H+ + OH-, Ka = 1.0...

INTRODUCTION The chemical and physical properties of substances are influenced by the way in which valence electrons are distributed and by the three-dimensional shape of the molecule or ion. X- ray and neutron diffraction, infrared, Raman and microwave absorption spectroscopy, as well as dipole moment measurements are used to ascertain the three-dimensional structure of a substance. Thus, techniques are available which can identify the geometry of substances. Results of these measurements generally...
