Question

naming covalent compounds
covalent compound:
pattern:
1st nonmetal + 2nd nonmetal
iupac naming rule:
(greek prefix)(name of 1st nonmetal) + (greek prefix)(stem name of 2nd nonmetal)ide
note: mono is never used as a greek prefix for the 1st element.
name the following compound:
ccl₄

Explanation:

Step1: Identify the elements

The first non - metal is carbon (C) and the second non - metal is chlorine (Cl).

Step2: Determine the prefixes

There is 1 carbon atom. Since it is the first element, we don't use "mono -". There are 4 chlorine atoms, so the prefix for chlorine is "tetra -".

Step3: Apply the naming rule

We combine the name of the first non - metal "carbon" with the prefixed name of the second non - metal "tetrachloride".

Answer:

Carbon tetrachloride
