Which one of the following reactions would produce t-butyl methyl ether in high yield?
swat32

Answer:

D) sodium t-butoxide + bromomethane

Explanation:

The alkoxide ion is a strong nucleophile, that unlike alcohols, will react with primary alkyl halides to form ether. This general reaction is known as <em>the Williamson synthesis</em>, and is a SN₂ displacement. The alkyl halide must be primary so the back side attack is not hindered, and the alkoxide ion must be formed with the most hindered group.

The mechanism can be seen in the attachment.

How would one convert 36 yd to centimeters (2.54 cm = 1 in)
ValentinkaMS [17]
I would go yards to feet, feet to inches, inches to centimeters. So 36 yards is 108 feet. There are 12 inches in a foot so 1,296 inches in 108 feet. Multiply that by 2.54 centimeters to get 3,291.84 centimeters in 36 yards.

A certain metal M forms a soluble sulfate salt M2SO4. Suppose the left half cell of a galvanic cell apparatus is filled with a 5
VikaD [51]

Answer:

Right

Explanation:

The given parameters are;

The soluble sulfate formed by the metal, M = M₂SO₄

In the galvanic cell formed by the metal M, we have;

The concentration of M₂SO₄ in the left half cell = 50.0 mM = 0.05 M

The concentration of M₂SO₄ in the right half cell = 5.00 M

In the galvanic cell, the metal 'M' will be dissolved into the solution with lower concentration as M²⁺ which is the left half cell, making the cell negative and the solution more concentrated

In the right half cell, the metal 'M²⁺' in the solution will be plated unto the electrode making the solution less concentrated and the electrode in the right half cell will be the positive electrode

Therefore;

The electrode which will be positive is the electrode in the right half cell.
