Write down the structural formulae of the following compound.
b. Cyclobutene

The given structures indicate the valency of carbon. Imagine that hydrogen atoms are added to these structures. Complete the given structures

Complete the table given below

(i) If an alkane contains ‘n’ carbon atoms, how many hydrogen atoms will be there?

(ii) If so, can you deduce a general formula for alkanes?

(i) What is the difference between the number of carbon atoms and hydrogen atoms in ${\mathrm{CH}}_4$ and  ${\mathrm{C}}_2{\mathrm{H}}_6$?

(ii) Is the difference same in the case of ${\mathrm{C}}_2{\mathrm{H}}_6$ and ${\mathrm{C}}_3{\mathrm{H}}_8$

Complete the table given below

• Analyse the table given above and find out how many hydrogen atoms would be present in an alkene with n carbon atoms.
• If so, can a general formula of alkenes be deduced? Try to write the general formula of alkenes?
• Check whether the alkenes given in the above table are members of a homologous series.
