Answer: The major product of the reaction between Hydrobromic Acid and 2-bromo-1-butene in the presence of ether and acid is 2,2-dibromobutane.
Explanation:
The mechanism of the reaction is supported by the Markovnikov's rule which explains that in the addition reaction of alkenes by hydrogen-halogen compounds, the incoming halogen substituent goes to the more substituted Carbon. It can also be stated that incoming hydrogen atom goes to the Carbon with more Hydrogen atoms.
The only case when the reverse of Markovnikov's rule takes place is when Hydrogen peroxide is present and the addition reagent is HBr.
This case is not like that and it simply follows the Markovnikov's rule.
I'll add an attachment of the reaction to this now.
The question is incomplete, here is the complete question:
Problem page in each of the molecules drawn below one chemical bond is colored red. Decide whether this bond is likely to be polar or not. if the bond is likely to be polar, write down the chemical symbol for the atom which will have more negative charge.
The image is attached below.
<u>Answer:</u>
<u>For carbon dioxide molecule:</u> The bond is considered as polar and the elecvtronegative atom is oxygen.
<u>For water molecule:</u> The bond is considered as polar and the elecvtronegative atom is oxygen.
<u>Explanation:</u>
There are two types of covalent bonds:
- <u>Polar covalent bond:</u> This bond is formed when difference in electronegativity between the atoms is present. When atoms of different elements combine, it results in the formation of polar covalent bond. <u>For Example:</u>
etc..
- <u>Non-polar covalent bond:</u> This bond is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. <u>For Example:</u>
etc..
<u>In carbon dioxide molecule:</u>
The given bond is present between C and O atom.
Electronegativity value of C = 2.5
Electronegativity value of O = 3.5
Electronegativity difference = (3.5 - 2.5) = 1
As, electronegativity difference is present. So, the bond is considered as polar and the elecvtronegative atom is oxygen.
<u>In water molecule:</u>
The given bond is present between H and O atom.
Electronegativity value of H = 2.1
Electronegativity value of O = 3.5
Electronegativity difference = (3.5 - 2.1) = 1.4
As, electronegativity difference is present. So, the bond is considered as polar and the elecvtronegative atom is oxygen.
