In terms of order of increasing basic ability, it is as follows. Phenylamine < ammonia < ethyl amine.
The reason why phenyl amine (containing a benzene ring) is a weaker base than ammonia is be...

In a haloalkane, not all of the bonds are the same. We have to consider the fact that the halogen atom (for instance a bromine atom) is more electronegative than either carbon or hydrogen...

Add sodium hydroxide solution to the substance and if a white precipitate is observed that does not dissolve in excess sodium hydroxide then there are magnesium ions in the substance.

Silver contains strong metallic bonds (a lattice of positive ions surrounded by a sea of delocalised electrons) which require large amounts of energy to break, therefore has a high melting point.

Chlorine has a lower boiling point as it is smaller in size than bromine. Chlorine has fewer electrons than bromine and fewer electron shells so chlorine is smaller in atomic radius. Size affects the str...
