Explanation:

Question 8

Organic compounds are generally defined as compounds containing carbon - hydrogen (C - H) bonds (with some exceptions like carbonates, cyanides, etc.).

• $\ce{CH3}$: Contains carbon and hydrogen, so it is an organic compound.
• $\ce{H2O}$: Contains hydrogen and oxygen, no carbon, so it is an inorganic compound.
• $\ce{C6H12O6}$: Contains carbon, hydrogen, and oxygen, has C - H bonds, so it is an organic compound.
• $\ce{NaF}$: Contains sodium and fluorine, no carbon, so it is an inorganic compound.

• Oxidation number: It is the charge an atom appears to have when electrons are assigned according to certain rules, and it is not related to what an empirical formula shows.
• System: This is a very general term and does not describe what an empirical formula shows about atoms in a molecule.
• Ratio: The empirical formula of a compound shows the simplest whole - number ratio of the atoms of different elements present in the compound. For example, the empirical formula of glucose ($\ce{C6H12O6}$) is $\ce{CH2O}$, which shows the ratio of C: H: O as 1:2:1.

Answer:

$\boldsymbol{\ce{CH3}}$, $\boldsymbol{\ce{C6H12O6}}$
