Introdução e Propriedades dos Hidrocarbonetos

Front

What is a hydrocarbon at the molecular level?

Back

Compound containing only carbon and hydrogen atoms

Front

A substance with 6 to 12 carbon atoms per molecule is most likely in which physical state at room conditions?

Back

Liquid under typical laboratory conditions

Front

You are selecting a solvent to dissolve a hydrocarbon sample. Which choice and reasoning would most likely succeed?

Back

Use a nonpolar solvent because hydrocarbons are largely nonpolar

Front

In the diagram, which class is an aliphatic hydrocarbon with only single bonds in an open chain?

Back

Alkane in open chain

Front

Using the diagram, identify the feature that distinguishes cyclic hydrocarbons from aliphatic ones.

Back

Closed carbon ring without terminals

Front

Refer to the structures. Which statement correctly classifies the aromatic example shown with two methyl groups on a benzene ring?

Back

Aromatic due to conjugated ring

Front

Using IUPAC rules, what is the correct name for the hydrocarbon shown: CH3–CH(CH3)–CH(CH2CH3)–CH2–CH3?

Back

3-ethyl-2-methylpentane

Front

For the saturated hydrocarbon CH3–CH(CH3)–CH2–CH2–CH(CH3)–CH–CH2–CH3 with an ethyl substituent on the central carbon, which parent chain length should be chosen by IUPAC?

Back

Eight carbons in longest chain

Front

Name the hydrocarbon H2C=CH–CH2–CH(CH3)–CH(CH3)–CH3 using IUPAC nomenclature.

Back

4,5-dimethylhex-1-ene

Front

Identify the correct IUPAC name for H2C=CH–C(CH3)=CH2, ensuring the double bonds receive lowest locants.

Back

3-methylbuta-1,3-diene
