Question

CH3CH2O is more stable than CH3COO- CH3COO is resonance stabilized CH3CH2O is more basic than CH3COO- The stronger the acid, the weaker its conjugate base. This is known as the: Kekule statement The reverse relationship The inverse relationship The acid-base relationship The weak acid relationship Te pKa of a weak acid HA is 3.50. The Ka of this acid is; 3.16 times 10-4 9.50 times 10-3 3.50 1.25 times 10-2 3.16 times 10-3 In the reaction (CH3)2CH++ OH rightarrow (CH3)2CHOH, OH- is: The electrophile The nucleophile The Arrhenius acid The Br6nsted-Lowrv acid The Lewis acid In a group, the most important factor in assessing acid strength is: electronegativity size resonance inductive effect hybridization effect
