Question

Find the oxidation number of carbon in glucose c6 h12 o6

Answer 1

For oxidation number of glucose, you have to know following things

If any element is bonded to element of its own kind, its oxidation state is considered as 0

General oxidation state of O, OH & H are -2, -1 & +1 respectively.

So the overall oxidation state of carbon atoms in glucose molecule is zero.

Answer 2

Answer:

ZERO

Explanation:

If any element is bonded to element of its own kind, its oxidation state is considered as 0

General oxidation state of O, OH & H are -2, -1 & +1 respectively.

So the overall oxidation state of carbon atoms in glucose molecule is zero.

C1  atom has one O, one C & one H atoms attached. Therefore its oxidation state  x+(−2)+(0)+(+1)=0∴x=+1  

C2,C3,C4,C5  all have one OH atom, two C atoms & one H atoms attached. Therefore each one’s oxidation state  x+(−1)+2(0)+(+1)=0∴x=0  

C6  atom has one OH, one C & two H atoms attached. Therefore its oxidation state  x+(−1)+(0)+2(+1)=+1∴x=−1  

Therefore, oxidation states of all carbon atoms are +1,0,0,0,0,-1 respectively. Since the addition of oxidation states of all carbon atoms is 0, the overall oxidation state of carbon atoms in glucose molecule is zero.
