Determine which alcohol in the given pair is more acidic. Give an explanation for your choice.
2-bromoethanol or 2-chloroethanol

• A. 2-bromoethanol is more acidic than 2-chloroethanol due to higher electronegativity of the Cl atom.
• B. 2-chloroethanol is more acidic than 2-bromoethanol due to higher electronegativity of the Cl atom.
• C. 2-bromoethanol is more acidic than 2-chloroethanol due to more polarizable nature of the bromine atom.
• D. 2-chloroethanol is more acidic than 2-bromoethanol due to resonance stabilization.

Answer: (B)
