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?
Why do corn cobs have long tassels ? View Solution Why do animals consume more energy as compared to plants View Solution Why do alcohols possess higher boiling points as compared to those of corresponding alkanes ? View Solution Why do He and H2 shows exceptional behaviour as compared to res...
Why do the molecules that have structures such as H_2C=C=CH_2 or HO-CH=CH_2 are unstable? Give reasons why it is important for the percentage atom economy of a reaction to be as high as possible. Explain why in a chemical reaction coefficients represent the relative mass...

Most carboxylic acids have a p Most carboxylic acids have a pKK aa close to 5. close to 5. Dr. Wolf's CHM 201 & 202 18-17 but carboxylic acids are far more acidic than alcohols but carboxylic acids are far more acidic than alcohols ...
So high boiling point means a long retention time. The solubility in the liquid phase. The more soluble a compound is in the liquid phase, the less time it will spend being carried along by the gas. High solubility in the liquid phase means a high retention time. The temperature of the...
