Question

Question 3 Which of the following series rank the acidity of the hydrogen atoms from most acidic to least. Ho b>a>c a>b>c

Answer 1

Solution:- "B" ( a > b > c )

Reason As the s character increases in a bond the electronegativity increases so as the acidic character. That's why the acidic trend is sp>sp₂ > sp₃ . so here sp₂ proton that is "a" will be highly acidic. Then b and c both are sp₃ protons but b is next to a sp₂ carbon so after losing the proton the negative charge can be stabilized by the resonance so it is more acidic than c.
