Explanation:
Monitor the temperature of the water with the thermometer. Stop heating the water once it nears the boiling point of 100 degrees Celsius. Add copper(II) sulfate and stir until the heated solution is saturated. When the solution is saturated, copper(II) sulfate will not dissolve anymore
Answer:
Structures of products have been given below
Explanation:
- It is an example of bromination reaction of toluene in presence of a catalyst e.g. Fe
- Methyl group in toluene is o/p-directing group. Therefore Br adds onto ortho and para position to methyl group in toluene.
- Reaction goes through electrophilic aromatic substitution. Here Br replaces one H atom from benzene ring.
- Here ortho product appears as a major one due to the fact that inductive effect of methyl substituent operates majorly at ortho position.
- reaction mechanism and structures of products have been shown below.
Alkali metals
Hydrogen only needs one more valence electron to fill it's out shell. So it belongs with the alkali metals.
