Current Question (ID: 10900)

Question:

$\text{The effect that can explain the given order of acidity of the carboxylic acids is-}$ $\text{Cl}_3\text{CCOOH} > \text{Cl}_2\text{CHCOOH} > \text{ClCH}_2\text{COOH}$

Options:

1. $+\text{I effect}$
2. $-\text{I effect}$ (Correct)
3. $+\text{E effect}$
4. $-\text{E effect}$

Solution:

$\text{Hint: } \text{Cl}_3\text{CCOOH} > \text{Cl}_2\text{CHCOOH} > \text{ClCH}_2\text{COOH}$ $\text{Step 1:}$ $\text{The order of acidity can be explained on the basis of the Inductive effect (-I effect). As the number of chlorine atoms increases, the -I effect increases. With the increase in -I effect, the acidic strength also increases accordingly.}$ $\text{Step 2:}$ $\text{Hence, option two is the correct answer.}$ $\text{The diagram shows electron-withdrawing effect of Cl atoms through inductive effect, with arrows indicating electron withdrawal from the carboxyl group. The more Cl atoms present, the stronger the electron-withdrawing effect, making the carboxylic acid more acidic.}$
