Homework Answers
Multiple questions, as per guideline first should be answered, first two questions are answered :
1. . Properties like volatility, melting point, solubility in water, and electrical conductivity can be utilized to classify substances as ionic or covalent.
Properties of Ionic Bonds
Low volatility
Strong Bonds
Usually Soluble in water
High Melting Point
Form a crystal lattice (Hard )
Properties of Covalent Bonds
High volatility
Weak bonds
Usually Insoluble in water
Low melting point
A. Covalent (Soft, it is non-conductive)
B. Ionic ( It is conductive and Non-volatile )
C. Covalent ( Soft, it is volatile )
D. Covalent ( volatile, soluble in cyclohexane )
2.
a) C is volatile and soft , so has lowest M.P. amongst unknowns.
b) 1st Highest M.P. = LiF ; Bond type : Ionic ; d EN= 3.0
2nd M.P. = CO ; Bond type : Polar conalent ; d EN= 0.9
3rd M.P. = H2 ; Bond type : Non-Polar conalent ; d EN= 0.0
