The trend in acidity for binary acids of Group 6 elements is: H,0 < H,S < H,Se < H,Te. c. Among the hydrohalic acids, only HF is the weak acid because of the weak H-F bond. く d. H.S is a weaker acid than H.O because AEN bet. H and S is greater than AEN bet. H and O.

Which of the following statement best explain why the acidity of carboxylic acids is greater than those of the alcohols? a. Alcohols behave as neutral compounds in aqueous solution. b. Alcohol has the ability to donate proton to becomes a negative ion called an alkoxide ion, RO– c. When a carboxylic acid donates its proton, it becomes a negatively charged ion, RCOO−, called a carboxylate ion which is more stabilized by resonance. d. The OH group in alcohol is less charged and often more difficult to release electron for chemical reactions.
