C2H6(CH3)-CHO (Isobutanal has alpha-hydrogen atom). Acetaldehyde, acetone and methyl ketones having CH3CO group undergo haloform reaction. The hydrogen atoms ofthe methyl group are first replaced by halogen atoms. This reaction is used as a test of CH3CO- group. Due to absence of CH3CO- group isobutanal does not give iodoform test.
