Question

How would you name the molecule ${{N}_{2}}{{O}_{4}}$ ?

Answer 1

For molecular compounds names would be given based on the number of atoms of each element present in the given compound. There will be a particular prefix based on the number of each atom present.

Complete step by step answer:
- In the question it is asked to write the name of the molecule ${{N}_{2}}{{O}_{4}}$ .
- The prefixes we are supposed to add to the name of the molecule are as follows.
- If a single atom is present then the prefix will be mono = 1.
- If two same atoms are present then the prefix will be di = 2.
- If three same atoms are present then the prefix will be tri = 3.
- If four same atoms are present then the prefix will be tetra = 4.
- If five same atoms are present then the prefix will be penta = 5.
- If six same atoms are present then the prefix will be hexa = 6.
- If seven same atoms are present then the prefix will be hepta = 7.
- If eight same atoms are present then the prefix will be octa = 8.
- If nine same atoms are present then the prefix will be nona = 9.
- If ten same atoms are present then the prefix will be deca = 10.
- Therefore the name of the given molecule is dinitrogen tetroxide (because two nitrogen atoms and four oxygen atoms are present in the given molecule ${{N}_{2}}{{O}_{4}}$ ).

Note: The letter ‘a’ at the end of the prefix should be replaced with ‘o’ letter while writing the name like ‘tetroxide’. The name of the molecule $N{{H}_{3}}$ is mono nitrogen trihydride ( because single nitrogen and three hydrogens are present).
