Consider the Acid Strengths of the Binary Hydrides of Group

Multiple Choice

Consider the acid strengths of the binary hydrides of Group VIA (16) H₂O, H₂S, H₂Se, and H₂Te.

A) The acid strength is largest for H₂O and decreases regularly due to hydrogen bonding.
B) The strengths of the acids are equal, other than H₂O which shows an anomaly due to hydrogen bonding.
C) The acid strength increases down the group because the bonds become weaker.
D) The acid strengths decrease down the group because of the inner electron shielding effect.
E) The order of acid strengths cannot be predicted.
