If the valencies of all the atoms are satis4ed by single bonds between them, then such carbon compounds are called saturated compounds. These compounds are normally not very reactive. However, another compound of carbon and hydrogen has the formula \(C_2H_4\) and is called ethene. One valency per carbon atom remains unsatisfied in ethene. This can be satisfied only if there is a double bond between the two carbons.
1. Saturated compounds have ____kind of bond.
(i) Single
(ii) Double
(iii) Triple
(iv) None of these
2. Ethene has_____bond.
(i) Single
(ii) Double
(iii) Triple
(iv) None of these
3. The valency of carbon atom in ethene is only satisfied if there is a bond between them. True or false?
(i) TRUE
(ii) FALSE
4. Are saturated compounds reactive?
(i) YES
(ii) NO
5. Are Alkynes compounds reactive?
(i) YES
(ii) NO
