Comparing the boiling points of: A) C3H8 B) C5H12 C) C2H5OH and identify the folowing statements as either True or False:
Dispersion forces only for (A) Boiling point (C) > Boiling point (A) (B) exhibits hydrogen bonding Boiling point (C) < Boiling point (A) (A) exhibits hydrogen bonding Boiling point (A) < Boiling point (B) Boiling point (B) < Boiling point (C) Dispersion forces only for (C) Boiling point (B) > Boiling point (C) Dispersion forces only for (B) (C) exhibits hydrogen bonding Boiling point (A) > Boiling point (B)

Respuesta :

Dispersion forces only for (A): True
Boiling point (C) > Boiling point (A): True, stronger intermolecular forces
(B) exhibits hydrogen bonding: False, no Hydrogen bonded to electronegative atom
Boiling point (C) < Boiling point (A): False, stronger intermolecular forces
(A) exhibits hydrogen bonding: False,  no Hydrogen bonded to electronegative atom
Boiling point (A) < Boiling point (B): True, stronger dispersion forces
Boiling point (B) < Boiling point (C): True, stronger intermolecular forces
Dispersion forces only for (C): False, also H-bonding
Boiling point (B) > Boiling point (C): False
Dispersion forces only for (B):  True
(C) exhibits hydrogen bonding: True
Boiling point (A) > Boiling point (B): False
