Chemistry Question on Coordination Compounds
The correct order of increasing boiling points of the following compounds is: Pentan-1-ol, n-Butane, Pentanal, Ethoxyethane
A
Ethoxyethane, Pentanal, n-Butane, Pentan-1-ol
B
Pentanal, n-Butane, Ethoxyethane, Pentan-1-ol
C
n-Butane, Pentanal, Ethoxyethane, Pentan-1-ol
D
n-Butane, Ethoxyethane, Pentanal, Pentan-1-ol
Answer
n-Butane, Ethoxyethane, Pentanal, Pentan-1-ol
Explanation
Solution
Boiling points are influenced by molecular weight, polarity, and hydrogen bonding: - n-Butane is non-polar and has the lowest boiling point. - Ethoxyethane has weak dipole-dipole interactions. - Pentanal has stronger dipole-dipole interactions. - Pentan-1-ol has hydrogen bonding, resulting in the highest boiling point. The correct order is n-Butane < Ethoxyethane < Pentanal < Pentan-1-ol.
