Explain the acidic natur of acetelenic hydrogen
Answers
Answer:
electrons has less energy near of the nucleus, and if we remember, the s orbital has a shape of sphere.
Hybridization it's important: Acetylene is sp, the etylen sp2 and ethane sp3.
So, we have:
The acetylene, with 50% of s character.
The etylene, 33,33% s.
Ethane, 25% s.
This show us that the acetylen act like been more electronegative (Remember that electronegativity it's the hability to mantein the electrons near of the nucleus), and the fact is that acetylene can to lead better with the negative charge, having, this way, the Hydrogen that goes out more easily.
You can to see that the acidicity is directly related with the ability of acetylene to support the negative charge
Answer:
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.
