Acid Strength

Question 1

Depends on?

Answer 1

Stability of the conjugate base anion;

Stability of anion depends on extent of dispersal of neg charge

Question 2

Dispersion of neg charge of anion depends on?

Answer 2

1. Types of groups

2. Resonance stability

Question 3

Explain EWG

Answer 3

Disperse the neg charge on anion;

Stabilised the conjugate base;

Question 4

Explain EDG

Answer 4

Intensifying the neg charge on anion;

Destabilise the resulting anion

Question 5

Explain resonance stability

Answer 5

• delocalisation of lp of e into benzene ring;
• resonance stability;
• disperse the neg charge on anion
• making phenoxide ion more stable
