Key Concepts

Systematic Naming of Inorganic Compounds

For inorganic compounds, systematic naming includes following agreed-upon conventions that often involve indicating oxidation states, names of ligands or polyatomic ions, and the overall composition of the compound. This systematic approach ensures that even complex inorganic species are named in a clear and unambiguous manner.

IUPAC Nomenclature

IUPAC nomenclature is the system established by the International Union of Pure and Applied Chemistry to provide unique and standardized names for chemical compounds. Its structured rules help convey the detailed composition and structure of compounds, ensuring clarity and uniformity in chemical communications worldwide.

Systematic Naming of Organic Compounds

Systematic naming for organic compounds involves identifying the longest continuous chain of carbon atoms, recognizing and naming substituents and functional groups, and assigning correct locants. This methodical approach allows chemists to deduce the molecular structure from the name and maintain consistency in naming across different compounds.

Transcript

00:06 In this problem, we are naming each of the compound shown.

00:09 So starting with a, we have an al -kine and a bromine.

00:13 The al -kine will take precedence, so we will number from the side that makes the al -kine the lowest number.

00:18 So we'll go from here.

00:19 One, two, three, four, five, six.

00:22 We have a bromine on carbon five, so that will be five -bromo.

00:27 And then our al -kine is on carbon two.

00:30 And we have six carbon, so that's hexine for the al -kine.

00:36 For part b, again, we're going to number so that the alkyne is the lowest it can be, and we're going to look for the longest carbon chain, which is right here.

00:46 So we'll number from this side.

00:48 One, two, three, four, five, six, seven, eight.

00:53 We have a methyl group on carbon five.

00:56 So that's five.

00:58 Methyl.

01:00 Two, because that's where our alkyne is.

01:02 And then we have eight carbons, so that's octane.

01:08 For part c, again, we're going to number from the lowest point that the alkyne can be.

01:15 So that is 1, 2, 3, 4, 5, 6.

01:20 We have 2 methyl groups on carbon 5, so that's 2 to dye methyl, die to make sure that we know there's 2.

01:28 And then our alkyne is on carbon 2, and we have 6 carbon, so that's hexine.

01:36 On part d, again, we're going to number so let the alkyne.
