Answer:
D. Anti-periplanar
Explanation:
In the <u>second step</u> of the intramolecular William Ether Synthesis mechanism (figure 1) we will have the attack of the negative charge of the oxygen to the carbon bond to the Br. At the same time the Br leaves, so a bond would be broken (the <u>C-Br</u> bond) and a bond would be formed (the <u>C-O</u> bond).
Now, this process can happen only if the <u>attack</u> and the <u>leaving group </u>has an anti configuration (figure 2). In an anti configuration the <u>nucleophile</u> and the <u>leaving group</u> would have <u>opposite directions</u>.
Answer:
Magnesium
Explanation:
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure.

Explanation:
1. For each of the following, convert the word equation into a formula equation, BUT do not balance!
a) Barium chlorate → Barium chloride + Oxygen
<u>1. Chemical formulas</u>
Barium chlorate:
- It is a salt: an ionic compound.
- Barium has oxidation state +2
- Chlorate is the ion ClO₃⁻
- Swap the oxidation numbers to write the subscripts: 2 goes to ClO₃ and 1 goes to Ba
- Chemical formula Ba(ClO₃)₂
- It is solid: Ba(ClO₃)₂(s)
Barium chloride:
- It is a salt: an ionic compount
- Barium has oxidation state +2
- Chlorine is in oxidation state -1
- Swap the numbers to write the subscripts: 2 goes to Cl and 1 goes to Ba
- BaCl₂
- It is solid BaCl₂(s)
Oxygen:
- It is a diatomic gas molecule
- O₂(g)
<u />
<u>2. Write the unbalanced molecular equation:</u>
- BaClO₃(s) → BaCl₂(s) + O₂(g)
b) Chlorine + Potassium nitride → Nitrogen + Potassium chloride
<u>1. Chemical formulas</u>
Chlorine:
- It is a diatomic gas molecule
- Cl₂(g)
Potassum nitride
- Potassium has oxidation state +1
- Nitrogen is with oxidation state +3
- Swap the oxidation states
- K₃N
- It is solid: K₃N(s)
Nitrogen:
- It is a diatomic gas
- N₂(g)
Potassium chloride
- It is a salt (ionic compound)
- Potassium has oxidation state +1
- Chlorine is in oxidation state -1
- Swap the oxidation numbers
- KCl
- It is solid: KCl(s)
<u>2. Write the unbalanced molecular equation</u>
<u />
- Cl₂(g) + K₃N(s) → N₂(g) + KCl(s)
c) Sodium nitride + Aluminum bromate → Aluminum nitride + Sodium bromate
<u>1. Chemical formulas</u>
Sodium nitride
- It is a salt (ionic compound)
- Sodium has oxidation state +1
- Nitrogen is with oxidation state -3
- Swap the oxidation numbers
- Na₃N
- It is in aqueous solution
- Na₃N (aq)
Aluminum bromate
- Salt
- Aluminum has oxidation state +3
- Bromate is the ion BrO₃⁻
- Swap the oxidation states
- Al(BrO₃)₃ (aq)
Aluminum nitride
- Both Al and N have oxidation state 3, which simply
- AlN(s). It is not soluble in water.
Sodium bromate
<u>2. Write the unbalanced molecular equation</u>
- Na₃N(aq) + Al(BrO₃)₃(aq) → AlN(s) + Na(BrO₃)₃(aq)
