Question

Wurtz's reaction is suitable for preparing unsymmetrical alkanes.
If true enter 1, else enter 0.

Answer 1

The Wurtz reaction is given below:

$R-X+2Na\to \left(R{)}^{-}\right(Na{)}^{+}$
This (R)- joins the 'R' from another R----X molecule and the (Na) joins the X part giving R----R + NaX. Thus, we are able to create only symmetric alkanes.
If you use two different alkyl halides then a mixture with small percentage of unsymmetric alkanes are produced but because of their very similar boiling points and their physical properties, they cannot be separated and thus, Wurtz reaction is not good for producing unsymmetric alkanes.
