Melting … Webthe use of DSC for measuring boiling points or generating vapor pressure curves. This preboiling vaporization tends to broaden boiling endotherms, may exhaust the specimen before the actual boiling point, or can self-pressurize a sealed specimen. Recent efforts to increase the utility of DSC for studying volatile specimens have shown that a ...

WebIt looks like you might have flipped the two concepts. Branching of carbon compounds have lower boiling points. An example of this would be neopentane - C(CH3)4 - which has a boiling point of 282.5 Kelvin and pentane - CH3CH2CH2CH2CH3 - which has a boiling point of 309 Kelvin. Pentane has the straight structure of course. Webshewskil gives a few values which in general run higher than the boiling points reported here. Like ethyl alcohol, isopropyl alcohol and water form a mixture boiling with constant composition for which Young2 gives 80.37 " as the boiling point and 87.90 the weight per cent. of the alcohol. Mixtures below this
WebIsopentane, also called methylbutane or 2-methylbutane, is a branched-chain saturated hydrocarbon (an alkane) with five carbon atoms, with formula C 5 H 12 or CH(CH 3) 2 (C … WebLiquids and Gases - Boiling Points - Boiling temperatures for common liquids and gases - acetone, butane, propane and more. Melting points of Hydrocarbons, Alcohols and Acids - Melting temperature (°C and °F) with carbon number up to C33. Net Refrigeration Effect - The quantity of heat absorbed from a refrigerated space.
Web1. number of carbons (increase in number of carbons, and hence molecular weight, increases BP) 2. Like you said, surface area. (increase in SA results increase in BP) 3. The strength of IMF. So I believe, that because nonane has more number of carbons AND more surface area, that's TWO factors that makes it have higher BP.
