See explanation
Explanation:
The mechanism for the formation of bromohexane from hexene has been clearly shown in the image attached to this answer.
Hexene is attacked by HBr and a carbocation is first formed as shown. The carbocation is flat and planar. it can be attacked on either face by the bromide ion.
Attack on either faces yields a racemic mixture of the R and S enantiomer as shown in the image.
You can use the mechanism shown to fill in the structures.
Answer:
Salt.
Explanation:
Salt=NaCl
Ionic bonds are made when the two elements are from different sides of the periodic table. On the left, we have our metals. On the right, we have our nonmetals. Sodium is a metal and Chlorine is a gas. Water, sugar, and carbon dioxide are covalent bonds because all the elements are from the right side of the periodic table. Hydrogen is a nonmetal too.
