2-Pentanone and Semicarbazide

2-Pentanone forms a derivative on treatment with semicarbazide. Note that semicarbazide has two -NH2 groups that might react with the carbonyl of the ketone to form semicarbazone. Explain why it reacts the way it does.

Industrial Scale Synthesis

If you were carrying out an industrial scale synthesis in which one step involve a haloform reaction to convert a methyl ketone into the corresponding acid having one less carbon atom, would you use NaOH and Cl2, NaOH and Br2, or NaOH and I2 reagent? Give reasons for your choice.
