General Properties of Organic Compounds - correct answer - Melt and boil at lower temperatures - As # C's and the MW increase, BP/MP increase - Flammable, unstable, especially triple bonds - Triple bonds can: Polymerize, Spontaneously react with, Oxygen, Explode. Keep triple bonds away from: Heat & Oxygen/Oxidizers - Presence of halogens increases stability - Many are water in-soluble i.e. they sink such as CCl4, MeCl2, PCBs etc - Some are polar if they contain hetero oxygen atom such ...
