Question

The empirical formula for glucose is-
A.${C_2}{H_4}{O_2}$
B.$C{H_2}O$
C.$CHO$
D.${C_2}H{O_2}$

Answer 1

Hint- Glucose is the fundamental kind of sugar in the blood and is the significant wellspring of vitality for the body's cells. Glucose originates from the food we eat or the body can make it from different substances.

Complete answer:

We will compose the empirical formula as-
An empirical formula is a formula that shows the elements in a compound in their lowest whole-number ratio. Glucose is an important simple sugar that cells use as their primary source of energy. Its molecular formula is ${C_6}{H_{12}}{O_6}$. Since each of the subscripts is divisible by 6, the empirical formula for glucose is $C{H_2}O$.
When chemists analyse an unknown compound, often the first step is to determine its empirical formula. There are a great many compounds whose molecular and empirical formulas are the same.
If the molecular formula cannot be simplified into a smaller whole-number ratio, as in the case of ${H_2}O$or ${P_2}{O_5}$, then the empirical formula is also the molecular formula.
How might we decide an exact empirical formula for a compound? How about we take a compound made out of carbon, hydrogen, and oxygen. We can break down the general measures of every component in the compound. At the point when we get a percent figure for every element, we now know what number of grams of each are in 100 grams of the first material. This permits us to decide the quantity of moles for every element. The proportions would then be able to be decreased to small whole numbers to give the exact empirical formula. In the event that we needed a molecular formula, we would need to decide the molecular weight of the compound.

Note: Glucose is carried to the cells through the bloodstream. Several hormones, including insulin, control glucose levels in the blood.
