What does halogenation involve?
Think about chemical reactions that replace atoms.
What are a-hydrogens in carboxylic acids?
Consider the carbon's placement next to the -COOH group.
What type of reaction allows for the introduction of halogens into carboxylic acids?
It starts with the letter 'H' and involves halogens.
True or False: The Hell-Volhard-Zelinsky reaction can occur without a-hydrogens.
Think about what the reaction targets specifically.
Given a carboxylic acid with the formula C4H8O2, predict the product when halogenated with Br2 and red phosphorus.
Focus on which hydrogen is being replaced.
Discuss how the introduction of different halogens (F, Cl, Br) could impact the acidity of the resultant a-halocarboxylic acids.
Consider electronegativity and its effect on stability.
