Give a structural formula for the carbocation intermediate that leads to the major product in the reaction of hydrogen chloride
with 2−methyl−2−butene.
1 answer:
Answer:
The major product forms in this reaction is 2-chloro-2-methylbutane
Explanation:
HCl reacts with 2-methyl-2-butene by forming a carbocationic intermediate followed by addition of chloride ion to the carbocation.
The carbocationic intermediate is formed in intermediate step should be most stable i.e. it should have highest number hyperconjugative hydrogen atoms.
The major product forms in this reaction is 2-chloro-2-methylbutane.
Reaction mechanism and structural formula of carbocation is shown below.

<u>Answer:</u> The metal having molar mass equal to 26.95 g/mol is Aluminium
<u>Explanation:</u>
- To calculate the number of moles for given molarity, we use the equation:
.....(1)
Molarity of NaOH solution = 0.5000 M
Volume of solution = 0.03340 L
Putting values in equation 1, we get:
- The chemical equation for the reaction of NaOH and sulfuric acid follows:
By Stoichiometry of the reaction:
2 moles of NaOH reacts with 1 mole of sulfuric acid
So, 0.01670 moles of NaOH will react with = of sulfuric acid
Excess moles of sulfuric acid = 0.00835 moles
- Calculating the moles of sulfuric acid by using equation 1, we get:
Molarity of sulfuric acid solution = 0.5000 M
Volume of solution = 127.9 mL = 0.1279 L (Conversion factor: 1 L = 1000 mL)
Putting values in equation 1, we get:
Number of moles of sulfuric acid reacted = 0.06395 - 0.00835 = 0.0556 moles
- The chemical equation for the reaction of metal (forming
ion) and sulfuric acid follows:
By Stoichiometry of the reaction:
3 moles of sulfuric acid reacts with 2 moles of metal
So, 0.0556 moles of sulfuric acid will react with = of metal
- To calculate the molar mass of metal for given number of moles, we use the equation:
Mass of metal = 1.00 g
Moles of metal = 0.0371 moles
Putting values in above equation, we get:
Hence, the metal having molar mass equal to 26.95 g/mol is Aluminium
