Why doesn't chlorine form hydrogen bonds even though it is more electronegative than nitrogen?

Chlorine has a higher electronegativity, but as it has a large atomic radius the electron density is spread out over a large area. This means that the electron density is too low to form proper hydrogen b...

Why is the melting temperature of Magnesium higher than that of Sodium?

More energy is required to break the metallic bonds in Magnesium, because: -Magnesium ions have a smaller ionic radius than Sodium ions so Magnesium is more closely packed -Mg2+ ions have a greater charge...

Why are Amines more basic than Amides?

The lone pair of electrons on the amine are more available to accept a proton and act as a base. This is because in amides, the carbonyl (C=O) group is highly electronegative, so has a greater power to dr...
