The answer is B. Flammability
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:
i think this is right!
Explanation:
An example of a single replacement reaction occurs when potassium (K) reacts with water (H2O). A colorless solid compound named potassium hydroxide (KOH) forms, and hydrogen gas (H2) is set free. The equation for the reaction is: 2K + 2H2O → 2KOH + H.
An example of a double replacement reaction is the reaction between silver nitrate and sodium chloride in water. Both silver nitrate and sodium chloride are ionic compounds. Both reactants dissolve into their ions in aqueous solution.
Chromatography separates things according to their weight.
Answer:
(slow)xy2+z→xy2z (fast) c step1:step2:xy2+z2→xy2z2
Explanation:
Step1: xy2+z2→xy2z2 (slow)
Step2: xy2z2→xy2z+z (fast)
2XY 2 + Z 2 → 2XY 2 Z
Rate= k[xy2][z2]
When the two elementary steps are summed up, the result is equivalent to the stoichiometric equation. Hence, this mechanism is acceptable. The order of both elementary steps is 2, which is ‘≤3’; this also makes this mechanism acceptable. Furthermore, the rate equation aligns with the experimentally determined rate equation, and this also makes this mechanism acceptable. Therefore, since all the three rules have been observed, this mechanism is possible.
