Why tertiary alkyl halides do not undergo wurtz reaction?
Tertiary alkyl halides do not undergo the Wurtz reaction because they do not have any active hydrogen atoms that can participate in the radical coupling step. Without an active hydrogen, the radical mechanism required for the Wurtz reaction cannot proceed.
In a hydrogen peroxide and yeast experiment what is the purpose of the cups with yeast and nothing?
The cups with yeast and nothing serve as a control in the experiment to compare the rate of reaction when hydrogen peroxide is added. By observing how the control cup behaves without the hydrogen peroxide, we can compare any changes in the cups with yeast and hydrogen peroxide to see the effect of the reaction.
The formation of product in a reaction is based on?
The formation of a product in a chemical reaction is based on the reactants' chemical properties, the reaction conditions (such as temperature and pressure), and the reaction mechanism, which includes the pathway and intermediates involved. The stability of the reactants and products, as well as the energy changes associated with bond breaking and formation, also play critical roles. Additionally, catalysts can influence the reaction rate and product formation without being consumed in the process.
Can ethene and bromine react without sunlight?
Yes, ethene and bromine can react without sunlight. The reaction occurs through an electrophilic addition mechanism, where bromine adds across the double bond of ethene to form 1,2-dibromoethane. This reaction can proceed in the dark, typically in a non-polar solvent, and is driven by the reactivity of the bromine molecule with the double bond of ethene.
If you need to reserve the following reaction in order for it to be an intermediate?
To classify a species as an intermediate in a chemical reaction, it must be formed during the reaction but consumed before the overall reaction is complete. Intermediates typically exist for a short duration and are not present in the final products. They often participate in subsequent steps of a reaction mechanism, facilitating the transformation of reactants into products. Thus, a valid reservation for a species to be termed an intermediate is that it must be transient and involved in the reaction pathway without being isolated in the final outcome.
Why is no indicator needed in redox titration experiment?
No indicator is needed in redox titration because the endpoint of the titration is determined by a change in the appearance of the titrand. This change can be detected visually, such as a color change, indicating the completion of the reaction without the need for an indicator.
Why do catalyst work without adding heat?
A catalyst changes the path of reaction mechanism and decreases the activation energy required by the reactants.
What is catylst?
In chemistry - a catalyst - is a chemical added to an experiment to speed the reaction - without combining with any of the chemicals present.

A scientist is planning to carry out an experiment on the effect of heat on the function of a certain chemical. which would not be an appropriate first step?
An inappropriate first step would be to start the experiment without conducting a literature review to understand existing knowledge on the chemical and its reaction to heat. This background information is essential for designing a relevant and informative experiment.
What is the value of the equilibrium constant at 25 and degC for the reaction between Cr(s) and Cu2 plus (aq)?
The equilibrium constant for the reaction between Cr(s) and Cu2+ (aq) cannot be determined without knowing the specific reaction equation. The equilibrium constant (K) is a unique value for each specific reaction at a given temperature.
Is the will valid without a residuary clause?
Yes, a will can be valid without a residuary clause. If assets are not specifically designated in the will, they will pass according to the laws of intestacy or another legal mechanism determined by the jurisdiction. It is still recommended to consult with a legal professional to ensure that your wishes are clearly outlined in your will.
What is the difference between a reflex and a feedback mechanism?
The difference between a reflex and a feedback mechanism is that the former is done without action by the brain but the latter is consciously done with feedback from the brain. A reflex is the reaction to external stimuli. Feedback to the brain can be given due to external or internal (within the body) reason.

What is a experiment without a variable?
An experiment has to have a varible, if it doesn't that it's probably and engineering experiment or robotics. I think its called a "control"
What are the key differences between the E1CB and E1 mechanisms in organic chemistry?
The key difference between the E1CB and E1 mechanisms in organic chemistry is the presence of a base in the E1CB mechanism, which facilitates the elimination reaction, while the E1 mechanism involves a unimolecular elimination without the need for a base. Additionally, the E1CB mechanism typically occurs in molecules with acidic hydrogen atoms, while the E1 mechanism is more common in molecules with stable carbocations.
