Organic Chemistry 2 Nomenclature Quiz

m-nitrostyrene refers to the meta isomer of nitrostyrene, while p-nitrostyrene is the para isomer, o-nitrostyrene is the ortho isomer, and nitrobenzene is a different compound entirely.

Tetramethylsilane is commonly used as an internal standard in NMR spectroscopy due to its low reactivity and lack of signal interference with common chemicals found in samples.

9,10-dibromophenanthrene is a derivative of phenanthrene with bromine atoms attached at the 9th and 10th positions, hence it is commonly known as Dibromophenanthrene.

Benzene anion radical has the chemical formula C6H5−, indicating the presence of a negative charge on the benzene molecule.

The correct answer refers to the position of the tert-butyl group on the benzene ring in the para (p-) position, hence leading to the IUPAC name 4-tert-butylbenzoic acid.

The correct IUPAC name for the compound is (p-ethylbenzyl)magnesium bromide, which indicates the presence of an ethyl group attached to the para position of the benzyl group along with a magnesium atom and a bromine atom. The other options are either missing the correct positioning of the ethyl group or using different alkyl groups altogether.

The compound [(C5H5)2Fe] is commonly known as ferrocene due to its molecular structure containing two cyclopentadienyl anions coordinated to an iron(II) center.

Furan is a heterocyclic compound with a five-membered ring containing four carbon atoms and one oxygen atom. Pyrrole, thiophene, and selenium are also heterocyclic compounds but they do not have the same ring structure as furan.

The correct chemical name for lithium di(1-cyclohexenyl)cuprate is Lithium 1-cyclohexenylcuprate, as the di(1-cyclohexenyl) part indicates the presence of two 1-cyclohexenyl ligands.

The correct chemical formula for the cyclopentadienyl anion is C5H5-. The anion consists of a five-carbon ring with alternating double bonds and a negative charge.

Tert-butyllithium, also known as 2-methylpropan-2-yl lithium, is a common organolithium reagent used in organic synthesis.

In this case, the correct IUPAC name is based on the Cahn-Ingold-Prelog (CIP) rules to assign priority to substituents on the chiral carbons.

The correct IUPAC name for the given compound is (2R, 3R)-2,3,4-trihydroxybutanal as per the stereochemistry of the molecule.

Semicarbazide is also known as Carbazic acid hydrazide. The other options provided are names of different chemical compounds that are not synonymous with semicarbazide.

2-Butanone diethyl acetal is commonly known as diethyl ketal in organic chemistry. It is a cyclic ketal compound with the formula C8H16O2.

12-crown-4 ether is a cyclic polyether compound commonly used as a ligand in coordination chemistry and as a phase transfer catalyst in organic chemistry.

Morpholine is a heterocyclic compound often used as a building block in organic synthesis.

The correct IUPAC name for C14H14O2 is benzyl p-methylbenzoate, as it follows the naming conventions for substituents and positions in organic compounds.

The correct IUPAC name for C6H13CN is 4-methylpentanenitrile because it consists of a pentane chain with a methyl group attached to the fourth carbon and a nitrile functional group at the end.

N,N-dimethylacetamide is a compound commonly used as a solvent in various chemical reactions and processes.

Acetic propanoic anhydride is a combination of acetic acid (ethanoic acid) and propanoic acid (propionic acid) in an anhydride form.

Diethyl malonate is the name of the compound itself, so the correct answer is simply diethyl malonate. The other options provided are not accurate names for this specific compound.

Sodium palmitate is the sodium salt of palmitic acid, commonly used as a food additive and in the production of soap.
