Transcript text: Question 33 of 39
Consider the following two compounds. Which of compounds is more acidic?
Compound $A$
Compound B
Which factor applies here?
Induction
Resonance
Orbital
Atom Bearing a Charge
Solution
Solution Steps
Step 1: Comparing Acidity
Compound A is more acidic than Compound B. Acidity increases as you go down the periodic table within a group. Sulfur is below oxygen on the periodic table, and since the sulfur atom is larger than the oxygen atom, the negative charge is more stabilized on the sulfur, making it a weaker base, and consequently, Compound A (with the SH group) a stronger acid.
Step 2: Identifying the Relevant Factor
The factor that explains the difference in acidity is the orbital in which the negative charge resides after deprotonation.
