The Wurtz-Fittig reaction synthesizes alkyl aryl compounds by reacting alkyl and aryl halides with sodium metal in dry ether: \[ C_6H_5Cl + CH_3Cl + 2Na \xrightarrow{\text{Dry Ether}} C_6H_5CH_3 + 2NaCl. \]
Distinction: The Wurtz reaction exclusively uses alkyl halides, whereas the Fittig reaction uses only aryl halides. Williamson Ether Synthesis is distinct from this process.
If the molar conductivity ($\Lambda_m$) of a 0.050 mol $L^{–1}$ solution of a monobasic weak acid is 90 S $cm^{2} mol^{–1}$, its extent (degree) of dissociation will be:
[Assume: $\Lambda^0$ = 349.6 S $cm^{2} mol^{–1}$ and $\Lambda^0_{\text{acid}}$ = 50.4 S$ cm^{2} mol^{–1}$]
