I always get confused with these. Can someone name all the IUPAC/Systematic/Common names we should know for plastics and acids

Don't explain how to name hydrocarbons, i just need the chloroethane? chloroethene? idk PVC thingo and muriatic acid, formic and stuff.

Thanks a lot.

idk what iupac is lol

Common name: Vinyl chloride
Systematic name: Chloroethene

Common name: Ethylene
Systematic name: Ethene

Common name: Styrene
Systematic name: Ethenylbenzene or phenylethene

Common name: Acetic acid
Systematic name: Ethanoic acid

Common name: Formic acid
Systematic name: Methanoic acid

Common name: Muriatic acid
Systematic name: Hydrogen chloride

^not sure about muriatic acid lol

They specifically name citric acid in the syllabus as well...

Common: Citric Acid
Systematic name: 2-hydroxypropane-1,2,3-tricarboxylic acid
Molecular formula: C6H8O7

I would definitely remember monomers/acids specifically named in the syllabus:

- Identify vinyl chloride and styrene as commercially significant monomers by both their systematic and common names.

- Identify acids including acetic (ethanoic), citric (2-hydroxypropane-1,2,3- tricarboxylic), hydrochloric and sulfuric acid

The tough ones are citric acid and styrene.

I have also seen tricks with acetic/ethanoic acid when they write the molecular formula as C2H4O2, rather than the more common CH3COOH (though this is only in school trial papers not past HSC papers).

Thanks guys, really helped a lot.

it seems the systematic names are basically the ones with the alkanes/alkenes thingo in it as well as the meth/eth thing.

I'll probably remember it a lot easer now.
I'm not really sure what IUPAC thing is, I just thought there were like three different sets of names. But now maybe its just two (common and systematic).

You need to know naming rules for Haloalkanes, Alkanols and Alkanoic acids.
Its good to know them for Alkanes and Alkenes .

For everything else the syllabus specifies what you should know and every one has written it above.

I'm pretty certain I know how to name it, but there is just one confusing matter that my teacher talked about.

She said that when you name haloalkanes the correct naming process (following IUPAC nomenclature) is naming it so that the side with numbering precedence is done according to the electronegativity, e.g. F is most electronegative

So when u have something like

--Cl H H F
H-C-C-C-C-H
--H Cl H H

(ignore the beginning dashes, used to fix spacing)

The correct name should be 3,4-dichloro-1-fluorobutane
But for the HSC since its simpler, it is trending towards doing both the naming and numbering alphabetically.
And in that case, it becomes 1,2-dichloro-4-fluorobutane.

Which one should I actually use in the HSC?

You add the numbers and which one gives the smallest total
3+4+1=8
1+2+4=7

So you use the second one.

There's THREE different names:
1. IUPAC
2. Systematic
3. Common

Systematic and common are self-explanatory, or at least, should be by this stage.

IUPAC and systematic are usually the same or similar but are occasionally different.

Generally speaking, knowing systematic and common is enough.
