Question

Arrange the following C-C bonds according to their reactivity.
(The topmost one being the least reactive)

• A. $C-C-C-C$
• B. $C=C$
• C. $C\equiv C-C$
• D. $C=C=C$

Answer 1

A saturated compound has a chain of carbon atoms linked together by single bonds whereas an unsaturated compound contains C-C double bonds or triple bonds. Unsaturated compounds are highly reactive. Order of reactivity of C-C bonds will be $\equiv >=>-$. If a compound has multiple unsaturations, it will be least reactive compared to the ones with a single saturation.
