Hydrogen bromide is a compound of the two elements hydrogen and bromine. It melts at $-87 °\mathrm{C}$ and boils at $-67 °\mathrm{C}$. 

i. Name two other compounds with bonding similar to that in hydrogen bromide. 

ii. Write formulae for these two compounds. 

Unlike diamond, graphite is soft and is a good conductor of electricity. Give a use of graphite that depends on one of these properties.

The general formula of three compounds $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ is ${\mathrm{C}}_{\mathrm{n}}{\mathrm{H}}_{2\mathrm{n}}$. $\mathrm{B}$ has the highest boiling point and $\mathrm{C}$ has the lowest boiling point.

Name the homologous series to which $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ belong.

Define homologous series of organic compounds. Mention any two characteristics of homologous series.

Why doesn't carbon share four electrons with other $\mathrm{C}$ atom, and exist as ${\mathrm{C}}_2$?

If graphite and fullerene have only 3 bonds, how they are stable?

Write the name of unsaturated hydrocarbons which contains: 
(a) one or more double bonds. 
(b) one or more triple bonds.
