A non stoichiometric compound is one where an exact integer ratio of atoms is not achieved. An example is FeO- all laboratory specimens are "iron deficient" with formals of about Fe0.8 O this is a feature of non -stoichiometric compounds their composition is variable within narrow limits- some of the iron is Fe3+, the crystal lattice has "defects" that accomodate them. (Pure FeO can be made but it is pyrophoric (may spontaneously in flame)
Ionic compounds: NaCl, KOH, CuSO4, etc. Any compound containing a metal and a non-metal. In ionic compounds, metals have positive ions (they lose electrons to the non metal) and non-metals have negative ions (as they gain electrons from the metal) Covalent compounds: CH4, BF3, NH3, all hydrocarbons/ all compounds containing only non-metals.
Ionic compounds are non-polar because they consist of ions (charged particles) held together by electrostatic forces. These compounds do not have a separation of charge within the molecule, which is characteristic of polar compounds.
Non-ionic means not carrying an electric charge. Non-ionic compounds or molecules do not contain positively or negatively charged ions, unlike ionic compounds which do. This property allows non-ionic substances to have different solubility and chemical characteristics compared to ionic compounds.
Yes, polar compounds typically travel farther in Thin Layer Chromatography (TLC) compared to non-polar compounds due to their stronger interactions with the polar stationary phase.
Non-aromatic compounds can be stable or unstable, as stability is determined by factors such as bond strength, molecular structure, and energy content. Non-aromatic compounds can exhibit varying degrees of stability, depending on their specific chemical composition and environment.
To perform stochiometric calculations
I think moles
yes
In a non-polar GC column, compounds with lower polarity elute first. Non-polar compounds are less attracted to the non-polar stationary phase of the column, so they move through the column faster than polar compounds.

Ionic compounds produce electrolytes; covalent compounds not.
chlorine forms ionic compounds with metals and covalent compounds with non-metals.

Non-ionic means not carrying an electric charge. Non-ionic compounds or molecules do not contain positively or negatively charged ions, unlike ionic compounds which do. This property allows non-ionic substances to have different solubility and chemical characteristics compared to ionic compounds.
Metals form compounds very easily with non-metals.
Yes, polar compounds typically travel farther in Thin Layer Chromatography (TLC) compared to non-polar compounds due to their stronger interactions with the polar stationary phase.
Non stoichiometric compounds do not match to law of definite proportions.
