Question

lactic acid me chiral carbon atom ki sankhya

Answer 1

1 chiral carbon is present..

Answer 2

The number of chiral carbon atoms in lactic acid is 1 .

Explanation:

Chirality

It is that carbon that has four different groups attached to it .like , it is shown below in case of Lactic acid .

It is an essential feature to make the compound optically active .

"Dis-symmetry and chirality is an essential feature for a compound to be optically active" .

Optically active

It is the substance that can rotate the plane of polarized light .

It can be rotated towards left or right .

If it is rotated towards left the substance is referred as "Laevo-rotatory".

If it is rotated towards right , the substance is referred  as "Dextro-rotatory".

Polarized light

It is the light in which particles of light align  only in one direction .
