why are acyl halides so reactive?
441485
Acyl chlorides are the most reactive carboxylic acid derivatives. The electronegative chlorine atom pulls electrons toward it in the C-Cl bond, which makes the carbonyl carbon more electrophilic. This makes nucleophilic attack easier. Also, the Cl- is an excellent leaving group, so that step is also fast.

This is because HCl and NaOH react in a 1:1 ratio. This forces HCl to be the limiting reactant (reagent) since it only has 1.5 mol versus 3.1 mol of NaOH.

CHCl3 is a stronger acid among them. The acidic strengths of the other two alkyl halides be compared their inductive effects.

Ketones are highly reactive, although less so than aldehydes, to which they are closely related. Much of their chemical activity results from the nature of the carbonyl group. Ketones readily undergo a wide variety of chemical reactions.

In alkyl halides, there exist dipole-dipole attractions where as in water van der waal's forces or the hydrogen bonding exists.. It is difficuilt for alkyl halides to break these hydrogen bonds, hence making them almost insoluble in water..

Anhydrides are less stable because the donation of electrons to one carbonyl group is in competition with the donation of electrons to the second carbonyl group. Thus, in comparison to esters, where the oxygen atom need only stabilize one carbonyl group, anhydrides are more reactive than esters.

SCH3- Since NaSCH3 is a weak base but a very strong nucleophile this means that alkyl halides undergoes an SN2 substitution rather and elimination is that right or not??

The sulphur dichloride oxide reacts with carboxylic acids to produce an acyl chloride, and sulphur dioxide and hydrogen chloride gases are given off. For example: The separation is simplified to an extent because the by-products are both gases.

They both form ionic bond with each other to have stable octets, but the Alkali metals are very reactive in water because they can lose their electron but the Halogens can't so their most common reaction is double displacement where they can gain an electron to have a full octet.

Generally bulky bases act in E2 reactions. They are electron rich but their really large size restricts them from acting as nucleophiles for steric reasons. ... Primary alkyl halides-always do only SN2 or E2. With a small base or nucleophile like ethoxide,SN2 will always be preferred as elimination is slowest in primaries.

It needs two more electrons to complete its octet.It therefore, acts as a Lewis acid catalyst in Friedel-Crafts alkylation and acylation reactions of benzene and other aromotic compounds.In these reactions, it helps to generate the electrophile (R+ or RCO+) which attacks the benzene / aromatic ring.

The sulphur dichloride oxide reacts with carboxylic acids to produce an acyl chloride, and sulphur dioxide and hydrogen chloride gases are given off. For example: ... You would obviously still have to fractionally distil the mixture to separate the acyl chloride from any excess acid or sulphur dichloride oxide.

The two most reactive groups of elements are the alkali metals and the halogens, because of their valence electrons. Those groups have 1 and 7 valence electrons, respectively, making them desperate to bond to something, to achieve a stable configuration of 8.

Organic Chemistry I Alkanes do not react with most reagents for two reasons. First, carbon‐carbon and carbon‐hydrogen single bonds are very strong due to good orbital overlap. Second, the carbon‐hydrogen bonds make alkane molecules neither acidic nor basic because the electronegativity of both elements is very similar.

In chemical terms, all of the alkaline metals react with the halogens to form ionic alkaline earth metal halides. ... The second ionization energy of all of the alkaline metals is also somewhat low. Beryllium is an exception. It does not react with water or steam, and its halides are covalent.

Aldehydes are typically more reactive than ketones due to the following factors. ... The carbonyl carbon in aldehydes generally has more partial positive charge than in ketones due to the electron-donating nature of alkyl groups. Aldehydes only have one e- donor group while ketones have two.

Because they are already in stable state or they already have stable electronic configurations so they dont want to disturb their stbale state by reacting with some other substance thats why they do not form compounds readily....
