In each of the following groups of substances, pick the one that has the given property. Justify your answer

a)Greatest viscosity: CH3CH2CH2CH3, HOCH2CH2OH or CH3CH2OH

b)Strongest Hydrogen bonding: PH3, NH3, SbH3

c)Greatest heat of vaporization: HF, HI, HBr, HCl

d)Smallest enthalpy of fusion: CO2, Li2O, H2O, MgO

Homework Answers

Answer #1

a)

Greatest viscosity : HOCH2CH2OH

hydrogen bonds increases the viscosity . in this molecule hydrogen bond capacity is more. so visocosity is more.

b)

Strongest Hydrogen bonding: NH3

NH3 only forms hydrogen bonding. remaining are not forming hydrogen bond.

c)

Greatest heat of vaporization : HCl

boiling point order : HF > HI > HBr > HCl .

which is having least boiling point , that has greatest heat of vapourization.

d)

Smallest enthalpy of fusion:   MgO
