How scientists/biologists/chemist came to know that glucose has four secondary alcohol instead of tertiary alcohol?... Please don't answer if you don't know...as you know my power xd​

Answer 1

Answer:

Glucose (C6H12O6) is a hexose -- a monosaccharide containing six carbon atoms. Glucose is an aldehyde (contains a -CHO group). Five of the carbons plus an oxygen atom form a loop called a "pyranose ring", the most stable form for six-carbon aldoses.

As my opinion, the scientists guessed that the glucose cannot have four tertiary alcohol because when it have tertiary alcohol it cannot form cyclic structure as well as it cannot have the 6carbon , 12 hydrogen and 6 oxygen

the proportionality varies... the scientists first tested the oxygen carbon hydrogen ratio in glucose

I collapse my mind and found this answer...it is wholly my own answer

thank you dear

It is mainly because we know glucose rotates ppl hence the carbon in the glucose would be showing chirality therefore if tertiary carbon would be there then chirality cannot be shown by glucose.
