Questions tagged [reactivity]
Applied to a chemical species, the term expresses a kinetic property in reference to another species. The tag should be applied to questions seeking answers with respect to the reactivity (or unreactivity) of a certain chemical compound, species, molecular entity and/or functional groups. It must not be applied to questions about the stability of certain chemical species.

Why is chlorine and not fluorine labelled as the most reactive halogen for halogenation?
The reactivity of halogenation in sunlight is as follows:
$$\ce{F2}>\ce{Cl2}>\ce{Br2}>\ce{I2}$$
So why does we often label chlorine as most reactive halogen towards halogenation reaction?

Does manganese reacts with water at "not" standard conditions?
In my answer, I stated that manganese is said to not react with water under normal conditions although some sources say it reacts with water to liberate hydrogen gas. Does it implies that it reacts ...

How is fluorine gas contained and transported, why aren't the metal cylinder and tube in this video attacked?
I included the GIF below as part of an answer to Can paper burn without oxygen or air?. It was made from the video Fluorine - Periodic Table of Videos.
I noticed that the cylinder containing the ...

Is silicon dioxide decomposition possible?
I was thinking about this, I made Gibbs free energy calculations and I can't figure out if
$$\ce{SiO2(s) -> Si(s) + O2(g)}$$
is actually possible, even at a ridiculous high temperature.

Why can't Grignard reagents react like Organolithium does (with acids)?
I'd read yesterday that Grignard reagents can't give ketones on reaction with carboxylic acids. It is because of the fact that Grignard reagent is a "super-base", and it will deprotonate the ...

Is benzyl chloride or allyl chloride more reactive?
What compound is more reactive, benzyl chloride [(chloromethyl)benzene] or allyl chloride (3-chloroprop-1-ene)? I know that both have a higher reactivity than alkyl and aryl chlorides.

The dependency on electron density in the reactivity order of electrophilic and nucleophilic additions
It is well-known that for electrophilic addition across an alkene, the reactivity increases when intermediate carbocation is more stable (eg. addition of $\ce{HBr}$ or acid-catalyzed addition of $\ce{...

How can you predict a double displacement reaction with no precipitate?
Is it possible to predict a double displacement reaction between two ions where the products remain in aqueous solution? I see how you can predict precipitation reactions if you know whether the ...

Can formaldehyde be stored at a higher temperature than room temperature?
I have studied that formaldehyde stored at temperature lower than room temperature convert into 1,3,5-oxane. So, it's not stored at colder temperatures.
But my question is - Can a similar degrading ...

How can nucleophilicity be estimated accurately?
Given the following: $\ce{CN-,OH-,SH-,I-}$. Determine the relative order of nucleophilicity in a protic solvent.
I know that, more the nucleophile is solvated by hydrogen bonding in a protic solvent,...

Is the variation in carbonation of soft drinks the variable that affects the effectiveness of the mentos reaction?
I went and bought a bottle of Fanta and some Mentos to replicate the famous youtube videos of the big fizzy reaction.
The result was dismal, it weakly foamed up and dribbled over the edge.
I tried ...

Grignards do transmetallation?
Grignards don't add to alkyl halides to create linear carbon extensions because Grignards do transmetallation rather than SN2 displacement of halide.
Is this correct?
I thought transmetallation a) ...

Do Grignard reagents react with amides?
Clearly the amide will be unreactive given the poor quality of the leaving group and poor electrophilcity due to delocalization. However, does it react with organolithiums for example?

Reaction of 1,2-diketones with periodic acid [closed]
$\ce{HIO4}$ can oxidise alcohols. But does $\ce{HIO4}$ undergo any reaction/act as oxidant with 1,2-diketones?
