Which of the following orders correctly represent decreasing acidic strength? — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

Order A is correct based on increasing $+I$ destabilization. Order B is correct because three fluorines outpull three chlorines, which outpull two chlorines. Order D is correct based on the increasing s-character ($sp > sp^2 > sp^3$), making the alkyne proton most acidic. Order C is incorrect because $F$ has a stronger $-I$ effect than $Cl$.
