The typical ratio for a carbohydrate is
a) CHO
b) C2HO
c) CH2o
d) CHO2
B) C2HO
It's called a carbohydrate because carbo stands for carbon (C) and hydrate stands for water (H2O). The typical ratio for monosaccharides is CH2O.
To determine the typical ratio for a carbohydrate, we need to understand its chemical composition. Carbohydrates are organic compounds composed of carbon (C), hydrogen (H), and oxygen (O) atoms. The general formula for carbohydrates is (CH2O)n, where "n" represents the number of repeating units or monomers.
Now, let's examine the options you provided:
a) CHO: This formula is missing the number 2, which signifies the presence of two hydrogen atoms per carbon atom. Thus, it does not represent the typical ratio for a carbohydrate.
b) C2HO: This formula is also missing the presence of oxygen (O) atoms. Therefore, it does not represent the typical ratio for a carbohydrate.
c) CH2O: This formula matches the general formula for carbohydrates ((CH2O)n), where "n" can be any positive integer. This represents the typical ratio for a carbohydrate, as it correctly shows the presence of carbon (C), hydrogen (H), and oxygen (O) in the 1:2:1 ratio.
d) CHO2: This formula suggests the presence of two oxygen (O) atoms but lacks the necessary hydrogen (H) atoms. Thus, it does not represent the typical ratio for a carbohydrate.
Based on the explanation above, the correct option is c) CH2O, which represents the typical ratio for a carbohydrate.
