Question

Which of the following is an example of catenation ?

• A. $C{H}_4$
• B. (b) and (c) above.
• C. $C_2{H}_6$
• D. $C_2{H}_4$

Answer 1

The correct option is B (b) and (c) above.

Carbon has catenation property due to which it has the tendency of self-linkage. It can extend to form long chains and rings.
Carbon can combine with other C-atom by single double and triple bond.
$C_2{H}_6$ and $C_2{H}_4$ has $C-C$ and $C=C$ bond, thereby making a longer chain.
Hence both are example of catenation.
