Chemistry Grade 10: Structural Representations of Organic Compounds

Vocabulary flashcards covering the condensed structural formula, bond-line representation, and polygon formulas for organic compounds as discussed in Grade 10 Chemistry.

Condensed Structural Formula

An abbreviated form of structural formula obtained by omitting some or all the dashes that represent covalent bonds.

Repetitive units condensation

A method where identical repetitive units are placed in parenthesis with subscripts to indicate their repetition, such as condensing hexane to $CH_3(CH_2)_4CH_3$.

Bond-Line Structural Representation

A notation where carbon and hydrogen atoms are not shown, and lines representing carbon-carbon bonds are drawn in a zig-zag fashion.

Terminals (Bond-Line)

Points in bond-line structures that denote methyl ($CH_3$) groups unless indicated otherwise by a functional group.

Line junctions (Bond-Line)

Points representing carbon atoms bonded to the appropriate number of hydrogen atoms required to satisfy the carbon atom's valency.

Heteroatoms

Atoms other than carbon or hydrogen that must be explicitly indicated in bond-line structural representations.

Hexyl bromide in Bond-Line

A structure where one hydrogen in a terminal $CH_3$ group is replaced by $Br$, leaving a $CH_2Br$ group.

Polygon Formula

A representation for cyclic compounds where corners represent carbon atoms and the sides denote carbon-carbon bonds.

Cyclic compounds

Organic compounds in which carbon atoms are joined in a ring rather than a chain.

Cyclopentane

A cyclic compound with the chemical formula $C_5H_{10}$.

Cyclopentanol

A cyclic compound with the chemical formula $C_5H_{10}O$, represented by a polygon structure.

Cyclohexane

A cyclic compound with the chemical formula $C_6H_{12}$.

Bromocyclohexane

A cyclic compound with the chemical formula $C_6H_{11}Br$, represented by a hexagon with a bromine atom attached.
