Answer:2-methylpropane
Explanation:
The structure of 2-methylpropane is contrasted with that of propane in the image attached. It is easy to see that 2-methylpropane contains a tertiary carbon atom which forms a stable radical. This stable radical formed will eventually lead to the yield of a single product which is 2-chloro-2-methylpropane. A tertiary radical is the most stable radical and often leads to the formation of a single product.
solve using the chemical equation and molar mass
Explanation:
I will solve this question assuming the reaction equation look like this:
<span>MnO2 + 4 HCl ---> MnCl2 + Cl2 + 2 H2O.
</span>
For every one molecule of MnO2 used, there will be one molecule of Cl2 formed. If the molecular mass of MnO2 is 87g/mol and molecular mass of Cl2 is <span> 73.0 g/mol, the mass of MnO2 needed would be:
Cl mass/Cl molecular mass * MnO2 molecular mass=
25g/ (73g/mol) * (87g/mol) * 1/1= 29.8 grams</span>
The answer to this question is C
