CHEM 102 Lecture Notes - Lecture 22: Phenyl Group, Triple Point, Alkyne
Document Summary
Map of the phase of a substance as a function of pressure (y) and temp (x) Solid, liquid and gas regions represents a stable state. Low temp and high pressure = solid. High temp and low pressure = gas. Represents a set of temperatures and pressures where the substance is in equilibrium between the 2 states on each side. Temp stops rising until all liquid is gas (going ) Pressure stops dropping until all liquid is gas (going ) Temp stops rising and melting occurs until everything is liquid. Represents temp and pressure above where a supercritical fluid exists. Ability to: form 4 covalent bonds, form double and triple bonds and tendency to catenate (form chains, branches or rings) Molecules w/ the same molecular formula but different structures. Shows number of each kind of atom and how they are bonded. Shows all c and h atoms and how they are bonded.
