Solution:
- Key Idea Chiral centre is also called stereo-centre or stereogenic center.
Linear structure of glucose is as follows :
Fischer formula Number of stereo-centre $\left(\mathrm{C}^{*}\right)=4$.
Cyclic structure of glucose are as follows :
Haworth formula Number of stereo-centre $\left(C^{*}\right)$ in each anomer $=5$.
