what exactly are the inorganic molecules from inorganic chemistry?

Question

what are the inorganic molecules that is often mentioned in inorganic chemistry?what exactly are they and what are their uses?

Answer 1

Kind of a broad question here. A lot of what I see being explained as "inorganic" molecules are not molecules at all.

Salts are not molecules. A molecule has a definite structure/connectivity relationship and can be isolated as an independent entity. For example it is possible to isolate a single molecule of benzene, ethyl alcohol or salicylic acid. These molecules retain their structure/connectivity relationship for all physical states. Molecules can be isolated as individual substances due to the greater covalent character of the bonds.

Salts, Ceramics and Alloys are not molecular.

Salts and ceramics are charge balanced systems with significantly more ionic character in their bonds than in molecular systems. You would not be able to isolate a molecule of NaCl for example.

Alloys are actually solutions of metals where by the mixing of the atoms takes place at the molecular level. Because electrons in metallic systems are so delocalized it is difficult to say there is true bonding.

So an inorganic molecule must contain atoms with significant amounts of covalent bonding, but not contain carbon.

Simple ones include: water (H2O) ammonia (NH3) Borane (which is a dimer, B2H6), any diatomic gas (N2, O2, Cl2), any hydrogen halide (HCl, HBr, HF), Silane (SiH4) Phosphene (PH3)

More complex are AlCl3 and GaCl3 (yes these are molecular and not salts!!) Phosphoric and sulfuric acid are molecular as well.

Very complex might be borazine (B3N3H6) the inorganic equivalent of benzene. Also most chemists refer to buckyballs (C60 and C70) as "inorganic" molecules because they are pure carbon, like graphite.

Answer 2

Organic chemistry involves Carbon (usually in in credibly long chains), and usually contain nonmetals. Inorganic chemistry involves all molecules that aren't organic. There are several inorganic molecules, and they all do different things and react differently. There are theoretically an infinite number of organic molecules because carbon atoms can string to themselves in endless chains.

Answer 3

Thr jury is still out on the difference between organic and inorganic in definition. Ultimately is really doesn't make a difference. I think it mainly matters when they are making school textbooks and they wish to separate them into separate subjects, but in reality there are many many overlaps in organic and inorganic

Answer 4

Organic compunds are usually composed of H,C,O,N, sometimes S, and halogens. Inorganic compounds are basically everything else, all metals, alloys, salts, most acids (three are organic acids like vinegar). For example propane C4H10 is organic, KBr is inorganic.

Answer 5

Organic molecules are those that are based on carbon and other non-metals. They usually use covalent bonding (where electrons are 'shared'). Eg: sugar.

Inorganic molecules are those that are based on metals and non-metals using ionic bonding, (where electrons are 'swapped'). Eg: salt.

Answer 6

obviously they INORGANIC!!! jk.

these are ionic, covlent (not with C), and simple elements.

Answer 7

things

Answer 8

carbonates,sulphates,chlorides,
bicarbonates,chlorates,nitrates,
nitrides,nitrites,phosphates,
chromite's,sulphides etc.,etc.
