Consider the following carbides:
CaC2IBe2CIIMgC2IIISrC2IV
Select the carbide which gives different products on hydrolysis than other carbides.
A.I
B.II
C.III
D.IV
1 AnswersTo determine which carbide gives different products on hydrolysis than the others, let's look at the hydrolysis reactions of each carbide:
CaC2 (Calcium carbide): Hydrolysis produces acetylene gas (C2H2).
Be2C (Beryllium carbide): Hydrolysis produces methane gas (CH4).
MgC2 (Magnesium carbide): Hydrolysis produces ethyne (acetylene) gas (C2H2).
SrC2 (Strontium carbide): Hydrolysis produces acetylene gas (C2H2).
As we can see, all carbides except Be2C (Beryllium carbide) produce acetylene gas upon hydrolysis. Therefore, Be2C gives different products on hydrolysis compared to the other carbides.
So, the correct answer is:
B. II
