Question

Which one of the following isomeric amines has the highest boiling point? (A) CH3-CH2-CH2-NH-CH3 (B) CH3-CH2-NH-CH2-CH3 (C) (CH3)2N-CH2-CH3 (D) CH3-CH2-CH2-NH2

Tardigrade Admin · Accepted Answer

Correct answer is (d) CH3-CH2-CH2-NH2

Q. Which one of the following isomeric amines has the highest boiling point?

$C H_{3} - C H_{2} - C H_{2} - N H - C H_{3}$

$C H_{3} - C H_{2} - N H - C H_{2} - C H_{3}$

$(C H_{3})_{2} N - C H_{2} - C H_{3}$

$C H_{3} - C H_{2} - C H_{2} - N H_{2}$

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

Correct answer is (d) $C H_{3} - C H_{2} - C H_{2} - N H_{2}$

Q. Which one of the following isomeric amines has the highest boiling point?

CH3​−CH2​−CH2​−NH−CH3​

CH3​−CH2​−NH−CH2​−CH3​

(CH3​)2​N−CH2​−CH3​

CH3​−CH2​−CH2​−NH2​

(CH3​)2​CH−NH−CH3​

Correct answer is (d) CH3​−CH2​−CH2​−NH2​

$C H_{3} - C H_{2} - C H_{2} - N H - C H_{3}$

$C H_{3} - C H_{2} - N H - C H_{2} - C H_{3}$

$(C H_{3})_{2} N - C H_{2} - C H_{3}$

$C H_{3} - C H_{2} - C H_{2} - N H_{2}$

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

Correct answer is (d) $C H_{3} - C H_{2} - C H_{2} - N H_{2}$
