WebThey have very high melting points. and boiling points. This is because large amounts of energy are needed to overcome their strong covalent bonds to make them melt or boil. Conduction of electricity 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.

WebFor example, copper is near the bottom of the reactivity series, and copper sulfate (CuSO 4), begins to decompose at about 200 °C, increasing rapidly at higher temperatures to about 560 °C. In contrast potassium is near the top of the reactivity series, and potassium sulfate (K 2 SO 4 ) does not decompose at its melting point of about 1069 °C, nor even at its … WebSteam distillation is also used for high boiling point substances that decompose before the boiling point is reached. In this case, instead of using a vacuum, the liquid in question is mixed with another, immiscible liquid. The presence of the second liquid causes both to boil at a temperature lower than the regular boiling points of either liquid.
