Question

CH ≡ CH + 2AgNO3 → AgC ≡ CAg + 2HNO3 represents which property of acetylene.
A. Basic
B Acidic. √

answer is acidic, now i want to ask that how we can know that in this question , acidic is the property of acetylene? help? someonoe told me that more bonds = more acidic is it right or not so answer it , thanks

Answer 1

That is a really poor question. Acetylene is a weak acid, and this reaction in that Ag2C2 can be considered a salt of the weak acid acetylene.

Answer 2

@bobpursley, i know it sir but , someone told me that its hno3 in equation so its acidic whats that means?

Answer 3

The H atoms on HCtriplebondCH are acidic. That is true. It is true also that the H atoms on H2C=CH2 are acid but they are weaker than on acetylene so that part you heard is true also. If you go one step further and look at H3CCH3 those H bonds are not acid enough to even consider them acid. And any comparison to HNO3 is hogwash.
The salts of acetylene are not all that stable and have been known to explode. Salts such as Ag, Cu, Pb, etc with acetylene have explosive properties.

Answer 4

@DrBob222 , thanks for reply sir, then what is proper way to describie it
