The Hell-Volhard-Zelinsky (HVZ) reaction involves the alpha substitution of a carboxylic acid by a halogen. This reaction requires an alpha hydrogen in the carboxylic acid.

Looking at the options:

1. Trichloroethanoic acid: This compound has no alpha hydrogens because all the hydrogens of the alpha carbon are substituted by chlorine atoms. Therefore, it cannot undergo HVZ reaction.

2. 2-methyl butanoic acid: This compound has alpha hydrogens and can undergo HVZ reaction.

3. Ethanoic acid: This compound has alpha hydrogens and can undergo HVZ reaction.

4. Propanoic acid: This compound has alpha hydrogens and can undergo HVZ reaction.

So, the compound that will not give HVZ reaction is Trichloroethanoic acid.
