Alkanes Practice Flashcards

A set of vocabulary flashcards covering the first 10 alkanes, their molecular formulas, general formula, and physical properties.

Alkanes

Nonane

The ninth alkane with the molecular formula $C_9H_{20}$, spelled as Nonane in the transcript.

Decane

The tenth alkane with the molecular formula $C_{10}H_{22}$.

Physical state of $CH_4$ to $C_4H_{10}$

Physical state of $C_5H_{12}$ to about $C_{17}H_{36}$

Liquids at room temperature.

Physical state of alkanes higher than $C_{17}H_{36}$

Solids.

Alkane Boiling Point Trend

More carbon atoms equals a higher boiling point.
