Covalent Bonding Flashcards
1
Q
What are the properties of graphite refer to structure
A
Weak bonds between layers so slide
Declosised electron conductor
Layers far apart so low density strong n lightweight
Strong covalent bonds to v high melting point
Insoluble covalent bonds too strong
2
Q
Explain the properties of diamond and refer to structure
A
High melting point Hard Vibrations travel easy Can't conduct cos no delocised electrons Won't dissolve in any solvent
3
Q
What is a dative covalent bond
A
Where both electrons come from one atom
Ammonium ion NH4+
Nitrogen donates pair of electrons to a proton H +
4
