Question

the number of chiral carbon in glucose is

Answer 1

There are four chiral carbons in the glucose.

• There chemical formula of the glucose is C6H12O6.
• So,it is clear that the glucose has a total of 6 carbons.
• Now, the carbons which are bonded with four different atoms will be considered as a chiral atom.
• The above mentioned criteria is satisfied by the second carbon, third carbon , fourth carbon and fifth carbon of the whole carbon chain of the glucose.
• The first carbon is excluded because it has a double bond with an oxygen atom. And, the sixth carbon is excluded because it's in CH2OH form.
• That's why,only 2nd,3rd,4th and 5th carbons which mean total four carbons will be considered as chiral carbons in the glucose.

Answer 2

Answer:

An asymmetric carbon atom (chiral carbon) is a carbon atom that is attached to four different types of atoms or groups of atoms. ... Molecules that cannot be superimposed on their own mirror image are said to be chiral like mirror image
