The following alcohols have to be ranked from strongest to weakest acid. C H 2 = C H C H 2 O H , CH 3 C H 2 O H , HC ≡ CCH 2 O H Concept introduction: If a base receives one proton, then the formed species is a conjugate acid whereas an acid lose one proton, then the formed species is a conjugated base. If an acid lose one proton, then the formed species is a conjugated base. Weak base forms stronger conjugated acid. Acidity of species depends on the electronegativity of atom attached to the acidic proton. Order of electronegativity of hybridization is s p > s p 2 > s p 3 so s p 3 hybridized molecule is weak acid.

Question

Chapter 2, Problem 46P

(a)

Interpretation Introduction

Interpretation:

The following alcohols have to be ranked from strongest to weakest acid.

CH2=CHCH2OH, CH3CH2OH, HC≡CCH2OH

Concept introduction:

If a base receives one proton, then the formed species is a conjugate acid whereas an acid lose one proton, then the formed species is a conjugated base.

If an acid lose one proton, then the formed species is a conjugated base. Weak base forms stronger conjugated acid.

Acidity of species depends on the electronegativity of atom attached to the acidic proton. Order of electronegativity of hybridization is sp> sp2 > sp3 so sp3 hybridized molecule is weak acid.

(b)

Interpretation Introduction

Interpretation:

The relative acidities of the alcohols has to be explained briefly.

Concept introduction:

If a base receives one proton, then the formed species is a conjugate acid whereas an acid lose one proton, then the formed species is a conjugated base.
