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.
Answer:
im only 11 but By convention in standard cell notation, the anode is written on the left and the cathode is written on the right. So, in this cell: Zinc is the anode (solid zinc is oxidised). Silver is the cathode (silver ions are reduced).
