Identify which of the hydrohalic acids is unlike the others, and why.
A) HF(aq), because it is the only strong acid
B) HCl(aq), because it is the only weak acid
C) HBr(aq), because it is a liquid at room temperature
D) HI(aq), because it does not display hydrogen bonding
E) HF(aq), because it displays hydrogen bonding

Question

Quizplus · Accepted Answer

HF(aq) is unique among hydrohalic acids because it can display hydrogen bonding due to the high electronegativity of fluorine. This property is not shared by HCl, HBr, or HI, making HF distinct in its physical and chemical behavior among the hydrohalic acids.
