Question

Which of the following could NOT be the formula for a carbohydrate? C6H12O6 C8H16O8 C10H20O10 C11H11O22

Answer 1

The answer is C11H11O22 this is not the formula for a carbohydrate

The general formula for a carbohydrate is (CH2O)n

Have a good day! =)

Answer 2

Option D

Step-by-step explanation:

The standard formula of carbohydrate is
`(CH_(2)O)_(x)`

Let us convert all the given options in the form of standard formula, we get -

a)
`C_(6)H_(12)O_(6) = (CH_(2)O)_(6)\\`

b)
`C_(8)H_(16)O_(8) = (CH_(2)O)_(8)\\`

c)
`C_(10)H_(20)O_(10) = (CH_(2)O)_(10)\\`

d)
`C_(11)H_(11)O_(22) is not equal to (CH_(2)O)_(6)\\`

Since, the ratio of carbon, hydrogen and oxygen in
`C_(11)H_(11)O_(22)` is not equal to 1:2:1.

Hence, option D is not correct.
