Name the following covalent compounds?

Question

i dont understand how this works.. if someone can show me how, and also why it works..that would be awesome.

1. CO2
2. CO
3. SO2
4. SO3
5. N2O
6. NO
7. N2O3
8. NO2
9. N2O4
10. N2O5
11. PCl3 (chlorine)
12. PCl5 (chlorine)
13. NH3
14. SCl6 (chlorine)
15. P2O5
16. CCl4 (chlorine)
17. SiO2
18. CS2
19. OF2
20. PBr2

Answer 1

Note: some of these materials have more than one name.

1 carbon dioxide
2 carbon monoxide
3 sulfur dioxide
4 sufur trioxide
5 nitrous oxide
6 nitric oxide
7 dinitrigen trioxide
8 nitrogen dioxide
9 dinitrogen tetroxide
10 dinitrogen pentoxode
11 phosporous trichloride
12 phosphorous pentachloride
13 ammonia
14 sulfur hexachloride
15 phosphorous pentoxide (phosporous V oxide)
16 carbon tetrachloride
17 silicon dioxide
18 carbon disulfide
19 oxygen difluoride
20 PBr2 (I've never heard of this; do you mean PBr3?)

PBr2 would be phosphorous dibromide PBr3 would be phosphorous tribromide

Answer 2

The compounds you listed are what are refered to as polyatomic ions. They're covalently bonded atoms that sort of act as a unit having an overall charge. These are often found as salts and such.

You kind of have to memorize their names so look them up and do a bit of memory work. But there are trends

Her eis what Wiki says:
There are two "rules" that can be used for the learning the nomenclature of polyatomic ions. First, when the prefix bi- is added to a name, a hydrogen is added to the ion's formula and its charge is increased by 1. It is a consequence of the hydrogen ion carrying a +1 charge. An alternate to the bi- prefix is to use the word hydrogen in its place: the anion derived from H+ + CO32−, HCO3− can be called either bicarbonate or hydrogen carbonate.

The second rule looks at the number of oxygens in an ion. Think of the -ate ion as being the "base" name, in which case the addition of a per- prefix adds an oxygen. Changing the -ate suffix to -ite will reduce the oxygens by one, and keeping the suffix -ite and adding the prefix hypo- reduces the number of oxygens by two. In all situations, the charge is not affected.

These rules don't always apply though so (while I NEVER reccommend it) memorization can be a good thing.

Answer 3

Co2 Compound Name

Answer 4

When naming covalent compounds you have to use prefixes. There are a few rules when naming these compounds. Take CO2 for example....the first rule would be that the first nonmetal keeps its elemental name. In this example, CO2, the first element is Carbon so keep that. Next rule is for the second element (O, oxygen)...the rule for the second element is that you have to use "prefixes" to count the number of atoms. 1 atom is "mono", two atoms is "di", three atoms is "tri", four atoms is "tetra", and five atoms is "penta" etc. So for our example CO2....it is called Carbon dioxide since it has 2 O atoms (di). CO would be called Carbon monoxide. SO2 is sulfur dioxide.

Answer 5

No2 Compound Name

Answer 6

3.) Dichloride something 4.) Carbon Monoxide 5.) Carbon Dioxide :) --- 6.) BF3 7.) NO 8.) I skipped this one, not sure of the prefix! 9.) N2O5 10.) forgot how many tetra is!

sorry that all i know

Answer 9

3. SO2 - Sulf"ITE"
4. SO3 - Sulf"ATE"

ite is smaller than ate
