Why do volatile organic compounds have weak intramolecular bonds? Why are chlorinated hydrocarbons dangerous to marine organisms? Why do alcohols boil at much higher temperatures than hydrocarbons of similar molecular weight? Why are trans fats bad for your body?
have higher boiling points than alkanes of equivalent molecular weight have. Like alcohols, amines with generally water-soluble. Primary and secondary amines form strong hydrogen bonds and are highly associated in the liquid state. Organic Chemistry ...
