Cumyl chloride reacts with azide ion in water to form a mixture of an alcohol and an alkyl azide. Predict the effects of each ch
ryzh [129]

Answer:

(a). Increase in the rate of Reaction.

(b). Increase in the formation of the alcohol.

(c). rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(d).rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(e). rate of reaction increases because of carbocation.

Explanation:

Important thing to note is that this reaction proceed with an SN1 mechanism.

Therefore; the rate of reaction depends solely on the concentration of alkyl azide.

(a). The concentration of the alkyl chloride is increased: rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(b) The concentration of the azide ion is increased: the effect is that there will be an increase in the formation of more of the alcohol.

c) The alkyl bromide is used instead of the alkyl chloride: the effect is that there will be rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(d) The reaction is carried out in 1:1 acetone water instead of pure water: the effect is that there will be the effect is that there will be rate of Reaction will increase that is to say more of the alkyl azide will be produced.

(e) The alkyl chloride shown below is used instead of cumyl chloride: rate of reaction increases because of carbocation.

Q1. Which reaction represents the half-reaction of lead (Pb) and the SRP value that could be found on an electric potential tabl
iris [78.8K]
The reaction that represents the half-reaction of lead Pb is    
    Pb2+(aq) + 2e- → Pb(s)   
and the SRP value on electric potential table is -0.13V.

To find the overall potential of a reaction, two half reactions can be added
together:
Oxidation:           Fe(s) → Fe2+(aq) + 2e-                               +0.44V
Reduction:          Pb2+(aq) + 2e- → Pb(s)                               - 0.13 V      
Overall reaction: Fe(s) + Pb2+(aq) → Pb(s) + Fe2+(aq)         +0.31V

This positive voltage for the overall reaction is spontaneous.

What would be the products for the reaction Br2 + KI →? (Just identify the correct products for the reaction. You do not need to
Savatey [412]

<u>Answer:</u> The products of the reaction will be I_2\text{ and }KBr

<u>Explanation:</u>

Single displacement reaction is defined as the reaction in which more reactive element displaces a less reactive element from its chemical reaction.

The general chemical equation for the single displacement reaction follows:

A+BC\rightarrow AC+B

The given chemical equation follows:

Br_2+2KI\rightarrow I_2+2KBr

Bromine element is more reactive than iodine element. Thus, can easily replace iodine from its chemical reaction.

Hence, the products of the reaction will be I_2\text{ and }KBr
