Hydrolysis of beryllium carbide gives acetylene

Vedclass · Answer

(D) The correct answer is $D$.$A$: $LiOH$ is a weaker base than $NaOH$ because the $Li-O$ bond is stronger than the $Na-O$ bond due to the smaller size of $Li^+$,making it harder to release $OH^-$ ions. This is correct.$B$: Salts of $Be$ undergo hydrolysis because $Be^{2+}$ has a high charge density and small size,which polarizes water molecules. This is correct.$C$: Calcium bicarbonate,$Ca(HCO_3)_2$,exists only in aqueous solution and is soluble in water. This is correct.$D$: Hydrolysis of beryllium carbide $(Be_2C)$ produces methane $(CH_4)$,not acetylene $(C_2H_2)$. The reaction is: $Be_2C + 4H_2O \rightarrow CH_4 + 2Be(OH)_2$. Thus,this statement is incorrect.
