Question

Identify the unsaturated compounds from the following :
$\left(i\right)$ Propane $\left(ii\right)$ Propene $\left(iii\right)$ Propyne $\left(iv\right)$ Chloropropane

• A. $\left(i\right)$ & $\left(ii\right)$
• B. $\left(ii\right)$ & $\left(iv\right)$
• C. $\left(iii\right)$ & $\left(iv\right)$
• D. $\left(ii\right)$ & $\left(iii\right)$

Answer 1

The correct option is D $\left(ii\right)$ & $\left(iii\right)$

(i) Propane $C{H}_3-C{H}_2-C{H}_3$
(ii) Propene $C{H}_3-CH=C{H}_2$

(iii) Propyne $C{H}_3-C\equiv CH$

(iv) Chloropropane $C{H}_3-CH\left(Cl\right)-C{H}_3$

Propene and propyne are unsaturated compound as they contain carbon-carbon multiple bonds.
