💡 Solution & Explanation

Correct option: \(\text{B}\). Preparation methods are selected by the target hydrocarbon: elimination forms alkenes/alkynes, reduction gives more saturated products, and coupling reactions build larger carbon skeletons. Recovered question text: 2. Reaction of Haloalkanes with Na (i) By Wurtz Reaction Example (1) (2) Note (1) Reactivity order of alkyl halide:- R–I > R–Br > R–Cl > R–F (2) We can form only symmetrical alkanes having even number of carbon atoms. Mixed-Wurtz reaction If two different alkyl halides are used, then it is known as mixed-wurtz reaction.  Methane cannot be prepared. 
