Define covalent bonding!
The sharing of outer electrons in order for atoms to obtain a full shell. There is an electrostatic attraction between shared electrons and positive nucleus.
What is dative covalent bonding?
When one atom donates 2 of its own electrons to another atom or ion to form a bond
What ae examples of dative covalent molecules? (Draw them out)
How does bond length affect bond enthalpy?
The shorter the bond the higher the bond enthalpy
Out of these carbon to carbon bonds, which one has the highest bond enthalpy and why?
Triple bond C has highest bond enthalpy (attractive force refers to the electrostatic attraction between shared electrons and the positive nucleus)
What bonds are present in simple molecules?
London forces
In general for giant covalent structures, what is its structure, solubility, conductivity and melting point? When possible explain the reasoning behind certain properties
Describe: structure, conductivity, solubility and other properties of graphite and explain why when possible
Describe the properties of graphene
Describe structure, conductivity and solubility of diamond and silicon dioxide?
