Question

Iodoform can be prepared from all except:

Options

• Isopropyl alcohol

• 3-methyl -2-butanone

• Isobutyl alcohol

• Ethyl methyl ketone

Answer 1

lodoform test can be given by methyl ketones and alcohols of the type R,CH(OH)CH₃ where R can be hydrogen also. So, isobutyl alcohol [(CH₃)₂CHCH₂OH] doesn’t show the iodoform test.
