Chapter 3, Problem 54d

Name each molecular compound. d. NO

Verified step by step guidance
1
Identify the elements in the compound: The compound NO consists of nitrogen (N) and oxygen (O).
Determine the type of compound: NO is a molecular compound, which means it is composed of nonmetals.
Use the appropriate naming convention for molecular compounds: Molecular compounds are named using prefixes to indicate the number of each type of atom present.
Apply the prefix for the first element: Since there is only one nitrogen atom, the prefix 'mono-' is typically omitted, so we simply use 'nitrogen'.
Apply the prefix for the second element: For the oxygen atom, use the prefix 'mono-' to indicate one atom, and change the ending to '-ide', resulting in 'monoxide'.
Combine the names: The name of the compound NO is 'nitrogen monoxide'.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Molecular Compounds

Molecular compounds are formed when two or more nonmetals bond together by sharing electrons. These compounds typically have distinct properties, such as lower melting and boiling points compared to ionic compounds. The naming of molecular compounds often involves using prefixes to indicate the number of atoms of each element present in the molecule.

Nomenclature of Compounds

The nomenclature of compounds refers to the systematic method of naming chemical substances. For molecular compounds, the names are derived from the elements involved, with prefixes like mono-, di-, tri-, etc., used to denote the number of atoms. For example, in the compound NO, 'N' stands for nitrogen and 'O' for oxygen, and the compound is named nitrogen monoxide.

Chemical Symbols and Formulas

Chemical symbols and formulas represent the elements and their proportions in a compound. Each element is denoted by a one- or two-letter symbol, with the first letter capitalized. In the case of NO, 'N' represents nitrogen and 'O' represents oxygen, indicating that the compound consists of one nitrogen atom and one oxygen atom.
