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.
Electrons are found in the cloud that's surrounded the nucleus of an atom
H2SO4 ---> 2H^+ + SO4^2-
Hence n H+ = 9 mols
Mass of H = nM = (9*1) = 9g
Alternately
mass of H2SO4= nM= 4.5*98= 441
Mass of H= mass h2so4 * molar mass of H/molar mass of h2so4
Mass of H= 441 * 2/98 = 9g
The chemical reaction of SiCl2→ Si +Cl2 is
A decomposition reaction
<u><em>Explanation</em></u>
- <u>A decomposition reaction</u> is type of chemical reaction which involve breaking down a compound into smaller compounds or individual elements.
- <em>SiCl2→ Si +Cl2 is a decomposition reaction because SICl2 is broken down into Si and Cl2</em>
- Decomposition reaction often involve input of energy in form of heat to break down compounds
