The correct decreasing order of Boiling points

Question

The correct decreasing order of Boiling points (A) R - CH 2- NH 2> RCOOH > RCH 2 OH (B) R - CH 2 OH > RCOOH > RCH 2 NH 2 (C) R - COOH > RCH 2 OH > RCH 2 NH 2 (D) RCH 2 OH > RCH 2 NH 2> RCOOH

B.P of carboxylic acid is highest due to strong intermolecular H- bonding. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/c72a51cc6b34d36f2175710e98041f28-.png" /> B.P of alcohol is higher than amines due, to high Electronegativity of oxygen than Nitrogen so alcohols form more strong H-bonding than amines ( RCOOH > R - OH > R NH 2/ text order of Boiling point )

Q. The correct decreasing order of Boiling points

$R - C H_{2} - N H_{2} > RCOO H > RC H_{2} O H$

$R - C H_{2} O H > RCOO H > RC H_{2} N H_{2}$

$R - COO H > RC H_{2} O H > RC H_{2} N H_{2}$

$RC H_{2} O H > RC H_{2} N H_{2} > RCOO H$

$B . P$ of carboxylic acid is highest due to strong intermolecular $H -$ bonding.

$B . P$ of alcohol is higher than amines due, to high Electronegativity of oxygen than Nitrogen so alcohols form more strong H-bonding than amines

$\frac{RCOO H > R - O H > RN H _{2}}{order of Boiling point}$

Q. The correct decreasing order of Boiling points

R−CH2​−NH2​>RCOOH>RCH2​OH

R−CH2​OH>RCOOH>RCH2​NH2​

R−COOH>RCH2​OH>RCH2​NH2​

RCH2​OH>RCH2​NH2​>RCOOH

B.P of carboxylic acid is highest due to strong intermolecular H− bonding. B.P of alcohol is higher than amines due, to high Electronegativity of oxygen than Nitrogen so alcohols form more strong H-bonding than amines order of Boiling point RCOOH>R−OH>RNH2​​

$R - C H_{2} - N H_{2} > RCOO H > RC H_{2} O H$

$R - C H_{2} O H > RCOO H > RC H_{2} N H_{2}$

$R - COO H > RC H_{2} O H > RC H_{2} N H_{2}$

$RC H_{2} O H > RC H_{2} N H_{2} > RCOO H$

$B . P$ of carboxylic acid is highest due to strong intermolecular $H -$ bonding.

$B . P$ of alcohol is higher than amines due, to high Electronegativity of oxygen than Nitrogen so alcohols form more strong H-bonding than amines

$\frac{RCOO H > R - O H > RN H _{2}}{order of Boiling point}$
