Vedclass · Answer

(A) The given compounds are:$(A)$ Diethyl ether derivative (Ether): $H_3C-CH_2-O-CH_2-CH_2-CH_3$ (Polar,dipole-dipole interactions)$(B)$ Pentane (Alkane): $H_3C-CH_2-CH_2-CH_2-CH_3$ (Non-polar,weak van der Waals forces)$(C)$ Pentan$-3-$one (Ketone): $CH_3-CH_2-CO-CH_2-CH_3$ (Highly polar,strong dipole-dipole interactions)$(D)$ Pentan$-2-$ol (Alcohol): $H_3C-CH(OH)-CH_2-CH_2-CH_3$ (Hydrogen bonding)Boiling point order depends on intermolecular forces:$1$. Hydrogen bonding (Alcohol) has the highest boiling point.$2$. Dipole-dipole interactions (Ketone) have higher boiling point than ethers.$3$. Ethers have higher boiling point than alkanes due to polarity.$4$. Alkanes (Non-polar) have the lowest boiling point.Thus,the order is: $B < A < C < D$.

List-$I$ (Test)	List-$II$ (Observation)
$A$. $Br_2$ water test	$I$. Yellow orange or orange red precipitate formed
$B$. Ceric ammonium nitrate test	$II$. Reddish orange colour disappears
$C$. Ferric chloride test	$III$. Red colour appears
$D$. $2,4-DNP$ test	$IV$. Blue,Green,violet or Red colour appear
