Alkanes are unsaturated hydrocarbons with multiple bonds.

Alkanes are aromatic compounds with a cyclic structure.

Alkanes are saturated hydrocarbons with only single bonds.

Alkanes contain double bonds between carbon atoms.

Alkanes react with halogens through ionic bonding.

Alkanes do not react with halogens at all.

Alkanes react with halogens by forming double bonds.

Alkanes react with halogens via free radical substitution.

Most alkanes are only liquids at high temperatures.

Most alkanes are gases or liquids at room temperature.

All alkanes are gases at room temperature.

Most alkanes are solids at room temperature.

The term 'saturated' indicates the presence of double bonds in alkanes.

The term 'saturated' refers to alkanes being soluble in water.

Saturated alkanes have fewer hydrogen atoms than unsaturated ones.

The term 'saturated' signifies that alkanes contain only single bonds and the maximum number of hydrogen atoms.

The boiling point of alkanes fluctuates randomly with carbon chain length.

The boiling point of alkanes remains constant regardless of carbon chain length.

The boiling point of alkanes decreases with increasing carbon chain length.

The boiling point of alkanes increases with increasing carbon chain length.
