Organic Compounds: Alkanes and Alkenes

Due to the smaller number of hydrogen atoms in the molecule, alkenes have (a)   melting and boiling points than their corresponding alkanes.

Alkenes are ___________ with water.

• non-miscible

• miscible

The boiling point of a branched alkane is (a)   than the boiling point of a straight-chain alkane with the same number of carbon atoms.

Alkenes are __________ compounds

• polar

• non-polar

The boiling and melting points of straight chain alkenes increase with an (a)   in the number of carbon.

Some cycloalkanes such as 1,2-dimethylcyclopropane exhibit geometric isomer called (a)   isomer. ­

Alkane with branched isomers are more (a)   than their unbranched structure.

Alkane with branched isomers have a smaller (a)   than their unbranched structure.

Alkanes do not form (a)   bonding with water molecules.

The density of alkanes increases as the molecular size of alkane (a)   .
