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.
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.
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.
In organic chemistry reactions, a 1,3 methyl shift occurs when a methyl group shifts from one carbon atom to another that is three carbons away. This rearrangement happens due to the movement of electrons, leading to the formation of a more stable molecule.
Potassium is more likely to form a cation, specifically the K+ ion, since it readily loses its valence electron to achieve a stable electron configuration.
Cis-2-butene is less stable than trans-2-butene because of steric hindrance - in the cis form, the two bulky methyl groups are next to each other, causing repulsion and strain in the molecule. This strain is relieved in the trans form where the methyl groups are on opposite sides of the double bond, leading to a more stable conformation.

Do a E1 elimination reaction (using a weak base, such as a hot alcohol). The initial primary cation formed is unstable, and a methyl shift will result in a more stable secondary cation. Elimination of the tertiary proton will give you 2-methyl-2-butene as the major product (zaitsev's rule - it is the more substituted product). Elimination of the primary proton will also get you some amount of 3-methyl-1-butene (the hoffman product).

No, it is exothermic because they form bonds to become more stable spontaneously
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.
i don't know go back to school:) it's a cation!
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.
Chlorine becomes an anion when it is ionized, as it gains one electron to achieve a more stable electron configuration.
3-methyl butanoic acid is more acidic than butanoic acid because the presence of the methyl group in 3-methyl butanoic acid increases the electron-withdrawing effect, making the molecule more acidic by stabilizing the conjugate base.
