Question

Please explain enantiomerisim and its condition?

Answer 1

Got a friend? Of course, you do

Explanation:

Take your right hand and try to shake the LEFT hand of your friend. Will it work...the answer is no, but what is the difference between left and right hands...they are usually structurally identical, but not geometrically identical. And of course you can shake his/her right hand with your right hand, or left with left. And so hands are handed, they have a chiral component (of course they do, we get the word `"chiral"` from the Greek `chiepsiloniotarho`, for hand....

And such conditions of chirality are a very important component of organic and inorganic chemistry; they influence chemical, and especially biochemical reactions. A carbon atom with FOUR substituents, `CR_1R_2R_3R_4`, can exist as LEFT-HANDED or RIGHT-HANDED stereoisomers depending on the geometry. The interchange of ANY TWO substituents results in the ENANTIOMER (and of course we do this on paper not in glass); interchange again, and you get the enantiomer of an enantiomer, i.e. the original isomer.

For another practical demonstration of chirality without a compliant twin, try putting your left hoof in your right boot, and vice versa. Will it work? But the left boot is STRUCTURALLY the same as the RIGHT BOOT....
