Binary Covalent Compound Nomenclature, Study notes of Chemistry

Guidelines for naming binary covalent compounds based on their chemical formulas. It covers prefixes, roots of nonmetals, and adding -ide to the end of the name. Examples of various binary covalent compounds are given, including their systematic names and memorized names.

What you will learn

  • What prefixes are used to indicate the subscript for the second element in a binary covalent compound?
  • Provide the systematic name for the compound PCl3.
  • What is the difference between systematic names and memorized names for binary covalent compounds?
  • Write the memorized name for the compound CO
  • How do you write the root of the name of the second symbol in a binary covalent compound?

Names

  • N 2

O

3

  • name starts with di
  • N 2

O

5

  • name starts with di
  • NO 2
  • no initial prefix
  • NO – no initial prefix

Naming Binary

Covalent Compounds

  • Write a prefix to indicate the subscript for the second element. (Remember to leave the “o” off of mono- and the “a” off of the prefixes that end in “a” when they are placed in front of a name that begins with a vowel.) - N 2

O

3

  • dinitrogen tri
  • N 2

O

5

  • dinitrogen pent
  • NO 2
  • nitrogen di
  • NO – nitrogen mon

Naming Binary

Covalent Compounds

  • Write the root of the name of the

second symbol in the formula. (See

the next slide.)

– N

2

O

3

  • dinitrogen triox
  • N 2

O

5

  • dinitrogen pentox
  • NO 2
  • nitrogen diox
  • NO – nitrogen monox

Naming Binary

Covalent Compounds

  • Add - ide to the end of the name.
    • N 2

O

3

  • dinitrogen trioxide
  • N 2

O

5

  • dinitrogen pentoxide
  • NO 2
  • nitrogen dioxide
  • NO – nitrogen monoxide

Name of

Br

2

O

7

  • Br and O both represent nonmetallic

elements, so this formula represents

a binary covalent compound.

  • di
  • dibromine
  • dibromine hept
  • dibromine heptox
  • dibromine heptoxide

Name of

CO

  • C and O both represent nonmetallic

elements, so this formula represents

a binary covalent compound.

  • No prefix at the beginning
  • carbon
  • carbon mon
  • carbon monox
  • carbon monoxide

Name of

H

2

S

  • H and S both represent nonmetallic elements, so this formula represents a binary covalent compound.
  • di
  • dihydrogen
  • dihydrogen mono
  • dihydrogen monosulf
  • dihydrogen monosulfide
  • dihydrogen sulfide or hydrogen sulfide

Name

NH

3

  • N and H both represent nonmetallic

elements, so this formula represents

a binary covalent compound.

  • Memorized name - ammonia

Forms of Binary

Covalent Names

  • prefix(name of nonmetal) prefix(root of name of nonmetal)ide (for example, dinitrogen pentoxide)
  • or (name of nonmetal) prefix(root of name of nonmetal)ide (for example, carbon dioxide)
  • or (name of nonmetal) (root of nonmetal)ide (for example, hydrogen fluoride)

Converting from
