Consider the Acid Strengths of the Binary Hydrides of Group

question 157

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.
