Asked by Jeff

I'm doing an intro to organic chem, and i'm looking at the functional groups of organic compounds. More specifically, I am looking at melting/boiling points. I keep reading that one has a greater m/b pt. than another, but another one has a greater m/b pt. that one but not another... etc..
Anyways, I'm getting quite confused. Could someone rank the following functinonal groups for m/b pts (highest to lowest or something)?
Alkane
Alkene
Alkyne
Halides
Alcohol
Ether
Amine
Aldehydes/Ketones
Carboxylic Acid
Ester
Amide

Frankly, I'm not sure you can generalize with so many functional groups. In some cases it is a matter of polarity and in some cases it's a matter of molar mass. How can one compare CH4 to CH3(CH2)30CH=CH2? Is that difference in mp/bp a matter of one being an alkane and the other an alkene or is it just a matter of molar mass?

Hydrochloric acid can be prepared using the reaction described by the chemical equation: 2 NaCl(s) + H2SO4(l) ----> 2 HCl(g) + Na2 SO4(s). How many grams of HCl can be prepared from 393 g of H2SO4 and 4.00 moles of NaCl?
