Which one of the following does not dissolve in conc. H2SO4 :–(a) CH

1.	Which one of the following does not dissolve in conc. H2SO4 :–(a) CH3 - C ≡C - CH3(b) Ch3 - CH2 - C ≡ CH(c) CH ≡ CH(d) CH2 ≡ CH2
Answer» Correct Option (c) CH ≡ CH Explanation : If CH ≡ CH were to dissolve in H₂SO₄ a bisulphite salt of vinyl carbocation H₂C = C+H would be formed. The more s-character in the pos itively charged 'C' , less stable is the carbocation and less likely to be formed.
