Answer:
Reversible chemical reaction favoring products.
Explanation:
Hello,
In this case, if we assume the following chemical reaction to be carried out:
We understand that it is under equilibrium conditions. In addition, based on the law of mass action, the present equilibrium constant is defined as:
Now, if Keq is greater than 1, it means that the concentration of the product B is greater than that of the reactant A, therefore, even though it is a reversible chemical reaction, it is favoring the formation of B it means the product(s).
Best regards.
Explanation:
acid --> HCN
base --> KCN
now
another base NaOH is added
we know that
base will react with an acid
so
OH- + HCN ---> CN- + H20
we can see that
HCN is used up , so number of moles of HCN will decrease
CN- is being formed , so number of moles of CN- will increase.
A false
B false
C false
D true
E false
No reaction would occur because copper is more active than silver and silver would be unable to donate electrons to copper.
Answer:
The glassware and solvent for the production of grignard reagent and its reaction should by dry and anhydrous so as to prevent the conversion of the grignard reagent into saturated alkane. Acetone, is not a good solvent for the generation of grignard reagent because it has the potential of forming alcohol.
Explanation:
Grignard reagent is a compound formed by the reaction of halide of alkyl or alkene with magnesium metal. This makes the compound more nucleophilic. Thus the availability of an electrophile around it will evoke a quick reaction. The presence of water in an acidic condition will generate hydroxonium ions which are highly electrophilic. There will therefore be an introduction of hydrogen ions to the grignard reagent and which will displace the MgBr leading to the formation of alkane.
Acetone tends to produce alcohol when they are exposed to grignard reagent, thus they are not appropriate to be used as solvent. This is due to the resultant highly electrophilic nature of the carbonyl carbon on the acetone, thus will react with the nucleophilic carbon on the grignard. The reaction can be represented as follows:
RMgBr + CH3(CO)CH3 + H (with hydrogen ions) >>>RCOH + Mg(OH)Br
