For example, there are ethanol and hexanol. Ethanol freezes at -114°C, I believe, while hexanol freezes at -44°C. But why does less energy need to be extracted from hexanol to freeze, when hexanol is longer and thus forms stronger VdWK than ethanol? So, why hexanol needs more energy added than ethanol to become liquid is logical, but I don't understand the reverse.

Loading...Hello, I don't understand why hydrofluoric acid has a high pks value when hydrofluoric acid can even attack glass According to the definition: the lower the pks value, the stronger the acid A strong acid such as HCl is characterized by having many protons and can therefore donate many of its protons because the bond…
Hey, Can one generally say that low-fat curd cheese, which has around 0.2g of fat per 100g, contains hardly any animal estrogen (hormones are apparently fat-soluble), even though fresh milk contains more than 3g of fat per 100g, and the curd cheese is made from milk? Milk does contain a fair amount of estrogen. Or…
So how often, please vote honestly.
I know that you shouldn't drink alcohol during your period, but if you do, would your period be longer or even shorter?
Just now two friends persuaded me to smoke something and now I'm super high and my dad must never find out
In principle, you argue well, but you forgot that VdW forces do not play a role. Right is: Intermolecular forces are crucial.
Here are H-bridge bonds (strong force) and VdW forces (weak).
In hexanol, the chains are longer and thus the stronger H bridges between the OH groups can no longer interact so frequently. Therefore, the intermolecular forces are smaller. The VdW forces cannot replace the “loss” on the interaction of the OH groups.
You only confuse yourself with the mindset. Imagine a difference in height. When you start up at the top and run down, you will logically pass the mark (melting point) that is the highest.
