Study Notes
Group 4A: Carbon/Crystallogens Family and Pharmaceutical Use Summary
- Department of Pharmacy's objective: comprehensively understand elements and compounds in Group 4A and their pharmaceutical use
- Carbon: used as a reducing agent in preparing metals, relatively inert at room temperature but combines with O2, X2, and other non-metals
- Ge and Sn: active metals, displace H from acids and combine with most metals
- Oxides and hydroxides of Sn and Pb: amphoteric, +4 oxides form stannates (SnO3-2) and plumbates (PbO3-2) when reacting with a base
- Carbon: fourth most abundant element, exclusively nonmetallic, essential in living matter, fundamental constituent of animal and vegetable tissue, exhibits catenation forming multiple bonds with itself
- Carbon allotropes: crystalline diamond (tetrahedral, purest native form), graphite (planar, used as lubricant)
