Question

Out of CH₃CH₂ – CO – CH₂ – CH₃ and CH₃CH₂ – CH₂ – CO – CH₃, which gives iodoform test?

Answer 1

CH₃CH₂ – CH₂ –CO –CH₃

Answer 2

Pentan-2-one (CH₃-CH₂-CH₂-CO-CH₃) give yellow precipitate of CHI₃ with NaOI, thats means it gives iodoform test.

Pentan-3-one (CH₃-CH₂-CO-CH₂-CH₃) does not give yellow precipitate with CHI₃ with NaOI, so Pentan-3-one does not give iodoform test.
