Question

Which of the following is less acidic among the given halogen compounds?

• A. \( \text{CHF}_3 \)
• B. \( \text{CHCl}_3 \)
• C. \( \text{CH}_3 \text{Cl} \)
• D. \( \text{CHBr}_3 \)

Hint:

The electronegativity of the halogen influences the acidity of the compound. Fluorine is less acidic than chlorine, bromine, or iodine.

Answer 1

The Correct Option is A

Step 1: Understand the acid strength of halogen compounds.
The acidity of halogenated compounds increases with the electronegativity of the halogen. Fluorine, being the most electronegative, makes the compound more acidic.
Step 2: Conclusion.
\( \text{CHF}_3 \) is less acidic compared to the others because the hydrogen is less acidic due to the weaker electronegativity of fluorine compared to other halogens. Final Answer: \[ \boxed{\text{CHF}_3} \]
