Why are chemical reactions of covalent compounds generally slow?
Because they contain mobile ions/free electrons
Because they contain strong covalent bonds
Because atomic reactions take place
Because they are highly soluble in water
Reactions between covalent compounds slow because-
Covalent compounds involve breaking and forming of new bonds.
Covalent compounds have strong bonds.
Hence, enough energy is to be provided to a molecule so that the bonds can be broken. This makes the reactions involving covalent compounds slow.
