Name each binary molecule.
a. CS2 Carbon Disulfide
b. N2O3 Dinitrogen trioxide
c. NF3 Nitrogen trifluoride
All are correct.
To name binary molecules, you need to use the prefix and suffix system. The prefix represents the number of each atom present in the molecule, while the suffix represents the type of bond between them. Here are the names of the given binary molecules:
a. CS2 - Carbon Disulfide
To name this molecule, we start with the name of the first element, carbon. The second element, sulfur, has the suffix "-ide" added to it. So, we get "disulfide" as the suffix. Putting it all together, we get "Carbon Disulfide."
b. N2O3 - Dinitrogen trioxide
Start with the first element, nitrogen. The prefix "di-" is used because there are two nitrogen atoms. Then, we have the second element, oxygen, with the suffix "-ide." So, we get "Dinitrogen trioxide."
c. NF3 - Nitrogen trifluoride
Again, start with the first element, nitrogen. The prefix "tri-" is used because there are three fluorine atoms. Then, we have the second element, fluorine, with the suffix "-ide." So, we get "Nitrogen trifluoride."
