Question

explain the acidic nature acetylenic hydrogen ?? what happeneds acetylene racts with H2o and hypobrimus acid and ozone ??​

Answer 1

Acetylene has two hydrogens attached to triple bonded carbon atoms i.e.., SP hybridized carbon atoms in which "s" character is 50%. With increase in s character acidic nature increases.So hydrogen attached to SP hybridized carbon atom is more acidic than those hydrogen's attached to SP2 and SP3 hybridized carbon atoms.
