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.
Which species is formed when the CH3N2 plus cation loses a nitrogen molecule?
When the CH3N2+ cation loses a nitrogen molecule, it forms the species CH3+ (methyl cation). This process involves the elimination of a nitrogen molecule (N2) from the original cation, leaving behind the methyl cation as the final product. The methyl cation is a positively charged species with a molecular formula of CH3+, consisting of a carbon atom bonded to three hydrogen atoms.
What is the chemical name of H3C?
Methyllium cation
What is the conjugate acid of CH3?
The conjugate acid of CH3 (methane) would be CH5+, which is an unstable species known as a methyl cation.
Is CH3- polar?
No, CH3CH3, or ethane, is not polar. It is considered nonpolar because it does not have strongly charged negative or positive hydrogen or carbon atoms.

What is another word for methyl?
Methyl is derived from methane. It is one carbon atom which is bonded to three hydrogen atoms. The methyl group comes in 3 forms: anion; cation or radical.
How many sigma bond orbitals are available for overlap with the vacant p orbital in methyl cation?
In methyl cation (CH3+), there are three sigma bond orbitals available for overlap with the vacant p orbital. These sigma bond orbitals originate from the three C-H bonds in the methyl group.
What is the conjugate acid of CH3?
The conjugate acid of CH3 (methane) would be CH5+, which is an unstable species known as a methyl cation.
Is CH3- polar?
No, CH3CH3, or ethane, is not polar. It is considered nonpolar because it does not have strongly charged negative or positive hydrogen or carbon atoms.
Why is cyclopropyl methyl cation more stable than tpm cation?
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.
Formation of 2-methyl-2-butene from dehydration of neopentyl alcohol?
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).
What is the structure for Methylamine hydrochloride?
The structure of Methylamine hydrochloride is CH3NH3Cl. It consists of a methyl group (CH3) attached to an amino group (NH2), which is protonated to form an ammonium cation (NH3+) by the chloride anion (Cl-).
How does methyl stearate compare to methyl oleate?
Methyl stearate is a saturated fatty acid methyl ester, while methyl oleate is an unsaturated fatty acid methyl ester. Methyl oleate has a higher degree of unsaturation due to a double bond in its carbon chain, making it more flexible and less rigid than methyl stearate. Additionally, methyl oleate may have different physical properties, such as a lower melting point, compared to methyl stearate.
What is the difference between molecular geometry and electronic geometry?
The molecular geometry and electronic structure of styrene and methyl methacrylate as well as corresponding radicals formed by the addition of a methyl radical to the -carbon of the monomer were determined using the density functional theory at the B3LYP/6-311+G** level. Results were in good agreement with the theoretical and experimental data available in the literature. Full optimized molecular geometry of methyl methacrylate showed the trans form of the molecule. Monomers transformed into corresponding radicals preserved the main structural parameters of substituents whereas bonds between substituents and adjacent radical carbon atoms shortened. It was found that the correlation of the theoretically calculated electronic parameters for monomers and the corresponding radicals with the Q and e parameters from the Alfrey-Price scheme strongly depends on the level of calculations. Application of the higher level of theory including the correlation effect changes the relationship discussed in the literature between energy (EY) of formation of a radical from the monomer, the experimental e parameter, and the Q parameter and monomer/average electronegativity, respectively. The total atomic spin density at the radical carbon atom correlated with the radical parameter P in the Alfrey-Price scheme was computed to be higher for the methoxycarbonyl-1-methyl-ethyl radical when compared with the 1-phenyl-propyl radical. These values are in good agreement with the localization energies and the P values determined from the kinetic measurements for macroradicals ending with styrene and methyl methacrylate monomer units. © 2001 John Wiley & Sons, Inc.
