Explain why compounds formed from non-metals normally do not conduct electricity and have a relatively low boiling point?
Explain, in terms of their structure and bonding, why the melting points of Calcium Fluoride (CaF2 1418°C) and Phosphorus Trifluoride (PF3 -151°C) are so different?
The hydrolysis of 1-chloropropane to produce propan-1-ol is much slower corresponding to hydrolysis of 1-iodopropane. Explain this observation.
Describe and explain the variation in boiling point of the gases Hydrogen Fluoride, Hydrogen Chloride, Hydrogen Bromide and Hydrogen Iodide.
Explain why the bond length of the following compounds is as followed: HF 92pm HCl 127pm HBr 141pm HI 161pm
