Chapter 4, Problem 53CTQ

Interpretation Introduction

Interpretation:Purpose of identification of most acidic hydrogens in below structures should be determined.

  

Concept introduction:Electronegative elements have tendency to attract electrons towards it. Since electrons are shared more towards electronegative element, it acquires partial negative charge on it. As a result, other bonded atom develops partial positive charge. Polarization in any molecule arises due to electronegativity difference between bonded atoms. Polarization that is caused by electronegative atom can induce polarization in neighboring bonds to very small extent. This effect is known as inductive effect. Due to this effect, hydrogen attached to positive atom become more acidic than that on neutral atom. This also explains more acidic nature of hydrogens attached to electronegative atoms as compared to other atoms.
