What is the coordination number for each of the following complexes or compounds?

a. [fe(gly)2(h2o)2]+
b. [cr(edta)]−
c. [pt(nh3)4]2+
d. [ag(nh3)2]no3

a. 4, b. 6, c. 4, d. 2

Explanation:

The coordination number (CN) of a complex of a compound is the number of bonds that a metallic ion does with the binders, which can be equal or not.

a. The metallic ion is the iron (Fe), and it's bonded to 2 gly and 2 H2O, thus, CN = 4.

b. EDTA is a hexadentate molecule, thus, it forms 6 bonds with the metal Cr, and CN = 6.

c. The metal is Pt, which has 4 bonds with NH3, thus CN = 4.

d. The metal is Ag, which forms 2 bonds with NH3. NO3 is bonded with the structure and not with the metal. Thus, CN = 2.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.

if you mean hydrogen and oxygen then water is the product
