Question

Comparing the boiling points of: A) C3H8 B) C5H12 C) C2H5OH and identify the following statements as either True or False:

Boiling point (B) < Boiling point (C)

(B) exhibits hydrogen bonding

(A) > Boiling point (B)

(A) exhibits hydrogen bonding

Boiling point (C) > Boiling point (A)

Dispersion forces only for (A)

Boiling point (C) < Boiling point (A)

Dispersion forces only for (C)

Boiling point (A) < Boiling point (B)

Boiling point (B) > Boiling point (C)

Dispersion forces only for (B)

Boiling point (B) < Boiling point (C)
True
This is correct because C forms hydrogen bonding and B has London dispersion forces

(B) exhibits hydrogen bonding
False
for hydrogen bonding to be formed there must be a hydrogen attached to Nitrogen , Oxygen or Fluorine

(A) > Boiling point (B)
False
Both have London Dispersion force but because of higher molar mass, dispersion force is higher in B

(A) exhibits hydrogen bonding
False
for hydrogen bonding to be formed there must be a hydrogen attached to Nitrogen , Oxygen or Fluorine

Boiling point (C) > Boiling point (A)
True
This is correct because C forms hydrogen bonding and A has London dispersion forces

Dispersion forces only for (A)
True

Boiling point (C) < Boiling point (A)
False

Dispersion forces only for (C)
False

Boiling point (A) < Boiling point (B)
True

Boiling point (B) > Boiling point (C)
False

Dispersion forces only for (B)
True
