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.
<u>Answer:</u> The correct answer is Option B.
<u>Explanation:</u>
Precipitate is defined as insoluble solid substance that emerges when two different aqueous solutions are mixed together. It usually settles down at the bottom of the solution after sometime.
For the given chemical equation:
The products formed in the reaction are calcium carbonate and potassium chloride. Out of the two products, one of them is insoluble which is calcium carbonate. Thus, it is considered as a precipitate.
Hence, the correct answer is Option B.
