the case of cyclopropylalkyl cation and substituted cyclopropyl cations is interesting. Cyclopropylmethyl cation has been found to be more stable than benzyl cation and the stability increases with each addition of cyclopropyl groups. This increased stability has been explained between the bent orbitals of cyclopropyl rings and the vacant p orbital of the cation carbon. The vacant p orbital lies parallel to C2-C3 bond of the cyclopropane ring and not perpendicular to it. Thus the geometry becomes similar to that of a cyclopropane ring conjugated with an olefinic bond.

The cyclopropylmethyl carbocation is very stable and is due to the ability of the bent bonds of the ring to donate electrons into the vacant p orbital on the carbon. This donation will translate into conjugation and therefore greatly enhanced stability. Dr Jim Romano CEO Romano Scientific CEO Orgoman.com

Strong electron donors make the cyclopropyl cation more stable than the allyl cation.

Are methyl cation is more stable than ethyl cation?

An ethyl cation is more stable because the carbon adjacent to the positively charged carbon has three sigma bond orbitals available for overlap with the vacant p orbital, whereas methyl cation does not have any sigma bond orbitals available for overlap with the vacant p orbital.


Why methyl amine is more basic than trimethyl amine?

Methyl amine is more basic than trimethyl amine because it is more stable. Basicity is based on the stability of a compound as well as the availability of the hydrogens present. With three methyl groups are far more unstable than one methyl group on a nitrogen, since all of the protons are pushing away from one another.


If 2-methyl 2-butene is mixed with H3O H2O what is the product?

it should be pretty stable... if I were forced to hazard a guess though, then 3-methyl-2-butanol would be really the only solution. The lone pair of the OH2 attacks the bond, then a H+ goes in and attacks the more substituted carbon (which used to be the 2-methyl one, and is now the 3-methyl one)


Why propene cation is more stable than propane cation?

Aromatic compounds are resonance stabilized. Hence if a compound is aromatic it is more stable. The main thing to note here is that AROMATICITY GIVES STABILITY TO A COMPOUND. Therefore cyclopropene is an aromatic compound and hence is more stable than propene.


What is the name of the compound HCOOCH3?

Historically, methyl-methyl ester. More modernly, the compound is called methyl methanoate.

Formation of 2-methyl-2-butene from dehydration of neopentyl alcohol?

The formation of 2-methyl-2-butene from the dehydration of neopentyl alcohol involves the removal of a water molecule. Neopentyl alcohol has three hydroxyl groups, and one of them is lost during the dehydration process, resulting in the formation of 2-methyl-2-butene as the final product. This reaction typically requires the use of an acid catalyst, such as sulfuric acid.


Is it possible for all reactions which have a carbocation intermediate to undergo rearrangement reaction to get a more stable cation?

No, in general

When a cation combins with an anion to form an ionic compound is the chemical reaction endothermic?

No, it is exothermic because they form bonds to become more stable spontaneously

What kind of ion is sodium most likely to forms?

Na+, which is a cation. Cations are positively charged; anions are negatively charged. You can remember because an is similar to and or add, which means that you are adding an electron, which is negatively charged. A cation has no electron added, it has one taken away.

A cation is an ion with a charge?

The answer to your question is yes. I assume you want to know what the charge is on a cation? A cation has a positive charge while an anion has a negative charge. remember it by this saying: plussy cats. get it? (as in plus-cations and a relative of a feline)
