Alkanes can be prepared by the reduction...

Alkanes can be prepared by the reduction of alkyl halides (preferably bromides and iodides). In one of the methods, reaction is carried out by dissolving metals such as
(i) `Zn` and dil. `HCl`
(ii) `Zn` and `CH_3)COOH`
(iii) `Zn` and `NaOH`
(iv) `Zn-Cu` or couple and alcohol

A

(i), (ii)

B

(iii), (iv)

C

(i), (ii), (iii)

D

(i), (ii), (iii), (iv)

Text Solution

Verified by Experts

The correct Answer is:
D
The metal `Zn` can be dissolved in any of these solvents. The function of metal is to provide electrons while the fundtion of solvent is to provide `H^(+)` ions.
