Why is a phenol more acidic than a regular alcohol? Group of answer choices
Aleks [24]

Answer:

a.Phenols have the ability to spread out the negative charge that forms.

Explanation:

This happens because of  the aromatic ring the phenols have. When loosing the proton, the anion formed have different resonance isomers due to the double bonds in the aromatic ring. This resonance makes the anion more stable and prevents the reaction going backwards.

On the other hand, regular alcohol doesn't have resonace and the reaction of loosing the proton goes leftward and righward: is in equilibrium.

That equilibrium decreases the acidity of the alcohol.

Which of the following chemical formulas show three molecules of a compound that has one
mr_godi [17]

The chemical formula : 3HgBr₂(Mercury(II) bromide)

<h3>Further explanation</h3>

Given

The chemical formulas of Mercury and Bromine

Required

The appropriate chemical formula

Solution

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

The number of molecules is determined by the coefficient in front of the compound

the number of atoms is determined by the subscript after the atom and the coefficient

Three molecules⇒ coefficient = 3

one atom of Mercury ⇒Hg

two atoms of Bromine ⇒ Br₂

The chemical formula : 3HgBr₂

Provide the reagents necessary to convert (S)-3-methyl-3-phenylpentanoic acid to (5)-3-methyl-3-phenylpentanamine.
8090 [49]

Answer:

1. SOCl2/pyridine

2. NH3

3. LiAlH4

4. H2O

Explanation:

In the conversion of  (S)-3-methyl-3-phenylpentanoic acid to (5)-3-methyl-3-phenylpentanamine, SOCl2/pyridine is first added to the  (S)-3-methyl-3-phenylpentanoic acid

This is then followed by the addition of NH3 is subsequently added followed by reduction using LiAlH4 which reduces the carbonyl carbon to an alkane. addition of water completes the mechanism and leads to the formation of the product.
