Answer:
-) 2-methylbut-2-ene
-) 2-methylbut-1-ene
-) 3-methylbut-1-ene
Explanation:
in this case, the hydration of alkenes is a <u>marknovnikov reaction</u>, this means that the "OH" group would be added in the <u>most substituted carbon</u> of the double bond. (Figure 1)
For 2-methylbut-2-ene the most substituted carbon is the <u>tertiary carbon</u> (the carbon in the right of the double bond), so we will obtain the desired molecule. In 2-methylbut-1-ene the most substituted carbon is again the <u>tertiary carbon</u> (the carbon in the bottom of the double bond), so we will obtain 2-methyl-2-butanol. Finally, for 3-methylbut-1-ene the carbocation would be formed on carbon 3, this is a secondary carbocation. We can obtain a most stable carbocation if we do a <u>hydride shift</u> (Figure 2). With this new molecule is possible to obtain 3-methylbut-1-ene.
I believe the correct answer is the geoshpere. I hope this was helpful.
From the information give, I'm going to assume the wave is in a vacuum...
You use the equation: f=
where c is the constant for speed of light (
so f=
f= 4.89 x
Hz (approximately)
The quantity pH stands for the negative logarithm of the H⁺ ions concentration in a solution. In equation form, pH = -log[H⁺], where [H⁺] is the concentration of hydrogen ion in molarity or moles/liter. Using this definition, the pH of the following substances are:
Oven Cleaner: pH =-log(10⁻¹³ M) = 13
Water: pH = -log(<span>0.0000007 M) = 6.15
Blood: pH = -log(</span><span>0.00000004 M) = 7.40
Vinegar: pH = -log(</span><span> 0.0063 M) = 2.2
The measure of the pH is important when it comes to reactions because pH is a strong factor. The net charge of a substance is a result of its pH. This charge is the basis of the degree of intermolecular forces like electrostatic attraction due to difference of charges by the substance and its substrate.</span>
Answer:
2-methylebutane
Explanation:
it is a hydrocarbon and there is a specific Rule for its nomenclature.
that is known as IUPAC naming system. According to it
- The compound that has all single bonds name ends on ane.
- Names according to the number of Carbons,
* For one carbon compound it is known as methane,
* For 2 ethane,
* For 3 propane
* For 4 Butane and so on.
- select the longest chain of compound
- Start numbering with lowest substituted position at carbon
- branch compound name as Iso and neo as whole
So keeping in mind the compound can be named as
2-methylebutane
- As the longest chain contain four carbon atoms so it will name as butane
- The substitution of methyl group is on C-2
*Note: it can also named as isopantane as it is branched and have five carbons but it could not be 3-isopentane.
