The following solution is suggested to handle the subject “organic chemistry Question 22: Arrange the following compounds in order of decreasing boiling point and explain…“. Let’s keep an eye on the content below!
Question “organic chemistry Question 22: Arrange the following compounds in order of decreasing boiling point and explain…”
Answer
This is the rank of all Ammine Compounds. The decreasing order of boiling points is 1>2>3>4.
This sequence is due to Hydrogen
Bonding. Propylenediamine having 2 -NH 2 groups. It has the greatest Hydrogen Bonding and therefore the highest boiling point of all 4 amines.
Butylamine is the most boiling of all N,N,diethylamines. It has 2 Ha in N.atoms, while N, N-diethylamine only has 1H. Because of this, Butylamine is more Hydrogen Bonded and therefore has a higher boiling point than N, N.-diethylamine.
N,N,N-diethylmethylamine has the lowest boiling point, because it has no H, attached to N atom, and thus can’t undergo any Hydrogen Bonding, and consequently has the lowest boiling point.
Conclusion
Above is the solution for “organic chemistry Question 22: Arrange the following compounds in order of decreasing boiling point and explain…“. We hope that you find a good answer and gain the knowledge about this topic of science.
