Vedclass · Answer

(C) $(i)$ Petrol and $CNG$ are cleaner fuels compared to diesel or coal,thus they cause less pollution. This statement is correct.$(ii)$ Alkanes containing a tertiary hydrogen atom can be oxidized to tertiary alcohols using $KMnO_4$. This statement is correct.$(iii)$ Kolbe's electrolytic method involves the electrolysis of sodium or potassium salts of carboxylic acids to produce alkanes. Methane $(CH_4)$ cannot be prepared by this method because the reaction requires at least two carbon atoms to form an alkane. This statement is incorrect.$(iv)$ Alkyl chlorides undergo reduction with $Zn$ and dilute $HCl$ to form alkanes $(R-Cl + 2[H] \xrightarrow{Zn/HCl} R-H + HCl)$. This statement is correct.Therefore,the correct statements are $(i)$,$(ii)$,and $(iv)$.
