Question 5 of 10
lesya [120]

Chemical equation represents a redox reaction :

2Li + MgCl₂ → 2LiCl + Mg

<h3>Further explanation</h3>

The oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number

Reaction

2Li + MgCl₂ → 2LiCl + Mg

Oxidation is an increase in oxidation number, while reduction is a decrease in oxidation number.

Oxidation

\tt Li\rightarrow Li^+(0~to~+1)

Reduction

\tt Mg^{+2}\rightarrow Mg(+2~to~0)

Answer:

Phenols do not exhibit the same pka values as other alcohols;

They are generally more acidic.

Using the knowledge that hydrogen acidity is directly related to the stability of the anion formed, explain why phenol is more acidic than cyclohexane.

Explanation:

According to Bromsted=Lowry acid-base theory,

an acid is a substance that can release H^{+} ions when dissolved in water.

So, acid is a proton donor.

If the conjugate base of an acid is more stable then, that acid is a strong acid.

In the case of phenol,

the phenoxide ion formed is stabilized by resonance.

C_6H_5OH -> C_6H_5O^- +H^+

The resonance in phenoxide ion is shown below:

Whereas in the case of cyclohexanol resonance is not possible.

So, cyclohexanol is a weak acid compared to phenol.
