Solution
The correct option is B A, B and C
Alkanes having odd carbons can be prepared in Sabatier - sendersen reaction.
In this reaction, alkenes add hydrogen in the presence of platinum or nickel catalyst, to form alkanes. The reaction termed as hydrogenation, is an exothermic reaction.
CH3−CH=CH2+H2Ni−−−→473KCH3−CH2−CH3
Alkanes having odd carbons cannot be prepared in
(A) Wurtz reaction
(B) Frankland reaction
(C) Kolbe's electrolysis
Wurtz reaction and Kolbe's electrolysis can be used for the preparation of alkanes having even carbon atoms.
When Zn is used in Wurtz reaction in place of Na, the reaction is named as Frankland method. In wourtz reaction a solution of alkyl halide in ether on heating with sodium gives alkane.
