Q. Compound reacting with alkaline $K M n O_{4}$

$C H_{3} - C ∣ H_{3} C ∣ O H - C H_{3}$

$C H_{3} - C ∣ O H H - C H_{3}$

$(C H_{3})_{3} C - C H_{2} O H$

none of the above

Only $1^{\circ}$ and $2^{\circ}$ alcohol are oxidised by alkaline $K M n O_{4} . 3^{\circ}$ alcohols do not react with alkaline $K M n O_{4}$
$2^{\circ} alcohol C H_{3} - C ∣ O H H - C H_{3} Alk. KMnO X_{4} ketone C H_{3} - C ∣∣ O - C H_{3}$
$Alk. KMnO X_{4} acid C H_{3} COO H$
