Binary molecular (covalent) compounds are formed as the result of a reaction between two nonmetals. although there are no ions in these compounds, they are named in a similar manner to binary ionic compounds. the nomenclature of binary covalent compounds follows these rules: the first element in the formula is given first, using the element’s full name. the second element is named as if it were an anion. ummarize the rules for naming binary molecular compounds. 32. define a binary molecular compound. 33. describe the difference between a binary acid and an oxyacid. 34. apply using the system of rules for naming binary molecular compounds, describe how you would name the molecule n 2 o 4 . 35. apply write the molecular formula for each of these compounds: iodic acid, disulfur trioxide, dinitrogen monoxide, and hydrofluoric acid. 36. state the molecular formula for each compound?

Binary molecular compounds are the compounds consisting of two non-metallic elements. Examples of binary molecular compounds include: NO2, HCl, HF, P2O5 e.t.c.

Rules For Naming Binary Molecular Compounds

Naming binary molecular compounds is quite easy,

1. The first element is given its name.

2. The second element is given its root name (such as, hydro, carb,ox, chlor e.t.c.) followed by suffix ide.

Name of N2O4 - Dinitrogen tetraoxide

Chemical Formula of;

 iodic acid: HI

disulfur trioxide: S2O3

dinitrogen monoxide: N2O

hydrofluoric acid: HF

Difference between Binary acid and an oxyacid

An oxyacid is an acid consisting of an oxygen atom bonded to a hydrogen atom and at least one other non-metallic element. Examples of oxyacids include HNO3, H2SO4 e.t.c.

Binary acids are the acids consisting of hydrogen atom bonded to a non-metallic element. Examples include HF, HCl, HI  e.t.c.

Explanation:Rrules for naming binary compounds.

1. The less electronegative element is written first.This is not always true for all elements.Nonmetals follow this order:C,p,N,H,S,I,Br,Cl,O,F.

2.The right numeric prefix is used example mono for 1 atom,did for 2 atoms,tri for 3 atoms,tetra for 4 atoms.etc

3. The second element is named after the first with the ending of the element's name changed to-ide then the right prefix is used for the second element.

4.Drop the 'a' in a prefix ending in one prior to the one starting with the vowel'o'. Example write tetroxide instead of tetra oxide.

32. A binary compound is a compound that contains two non metals.

33. A binary acid is a compound that contains a hydrogen atom that is bonded to a non metal in its molecule.They are called hydracids.The general formular is H-X.Examples are HCl,H2S, etcwhile oxyacid are compounds that are composed of hydrogen,oxygen and other elements in the molecule. An eample is HClO3.

34. N2O3 will be named dintrogentetroxide.This is because it is a covalent compound and will follow rule 2 by putting the right numeric prefix based on the number of atoms of nitrogen and oxygen in the molecule.The 'a"at the end of tetra dropped because of the vowel 'o'in the next letter.

35. a. Molecular formulae of iodic acid is HIO3

b.Molecular formulae for disulfurtrioxide is

S2O3

c.Molecular formulae for dinirtrogenmonoxide is N2O

d. Hydrogenchloric ice HCl
