9.3 - Structural formulas

Front

What is a structural formula?

Back

A structural formula is a representation of a molecule that shows the arrangement of atoms and the bonds between them.

What is the difference between a condensed formula and a line structural formula?

Back

A condensed formula shows the atoms in a molecule grouped together, while a line structural formula uses lines to represent bonds and shows the arrangement of atoms in a more visual format.

What does IUPAC stand for in chemistry?

Back

IUPAC stands for the International Union of Pure and Applied Chemistry, which is responsible for naming chemical compounds.

How do you determine the number of hydrogens in a hydrocarbon?

Back

The number of hydrogens in a saturated hydrocarbon can be determined using the formula CnH(2n+2), where n is the number of carbon atoms.

Front

What is the significance of the longest carbon chain in naming a compound?

Back

The longest carbon chain determines the base name of the compound and is crucial for applying IUPAC nomenclature rules.

Front

What is a double bond in organic chemistry?

Back

A double bond is a type of chemical bond where two pairs of electrons are shared between two atoms, commonly found in alkenes.

Front

What is the role of functional groups in organic compounds?

Back

Functional groups are specific groups of atoms within molecules that determine the chemical properties and reactivity of the compound.

Front

What is the difference between primary, secondary, and tertiary carbon atoms?

Back

Primary carbons are attached to one other carbon, secondary to two, and tertiary to three other carbons.

Front

What is a geometric isomer?

Back

Geometric isomers are compounds with the same molecular formula and connectivity but different spatial arrangements of atoms.

Front

How do you identify a branched alkane?

Back

A branched alkane has one or more carbon chains that are not in a straight line, indicating the presence of side chains or substituents.
