Melting point of solid ch3br
WebCH3Br is quite much more heavy molecule compared to CH3F (over 2,5 as heavy). As CH3F does not really form hydrogen bonds (as there is no hydrogen bond donor in the molecule) and a slight increase in polarity does not really have that large effect in the intermolecular forces. So the weight is the main factor here. Web16. Butter melts over a range of temperature, rather than with a sharp melting point. Butter is classified as a/an. A) metallic crystal. D) amorphous solid.

WebBromoform (CHBr 3) is a brominated organic solvent, colorless liquid at room temperature, with a high refractive index, very high density, and sweet odor is similar to that of chloroform. It is one of the four haloforms, the others being fluoroform, chloroform, and iodoform. Currently its main use is as a laboratory reagent.

Because the boiling points of nonpolar substances increase rapidly with molecular mass, C 60 should boil at a higher temperature than the other nonionic substances. The predicted order is thus as follows, with actual boiling points in …
WebNow let’s talk about the intermolecular forces that exist between molecules. Intermolecular forces are much weaker than the intramolecular forces of attraction but are important because they determine the physical properties of molecules like their boiling point, melting point, density, and enthalpies of fusion and vaporization. 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.
