Which of the following does not answer iodoform test?

Options

A. a) n-butyl alcohol
B. b) sec-butyl alcohol
C. c) Acetophenone
D. d) Acetaldehyde

Answer

A

Iodoform test is given by the compounds containing
`CH_(3)CO-` group or `CH_(3)overset(|)(C)HOH` group.
`CH_(3)CHO+3I_(2)+3NaOHrarrundersetunderset("iodoform")(("yellow ppt"))(CHI_(3))+HCOONa+3NaI+3H_(2)O`
`because n` butyl alcohol `(CH_(3)CH_(2)CH_(2)CH_(2)OH)` does not give iodoform test because it does not possess the `CH_(3)CO-` or `CH_(3)overset(|)CHOH` group.
