Is ethyl carbocation more stable than isopropyl carbocation?

Shown below are the resonance forms of the isopropyl carbocation (2), a secondary carbocation. Thus, the net charge of +1 is delocalized over a greater number of atoms in the isopropyl carbocation than in the ethyl carbocation. The isopropyl carbocation should, therefore, be more stable than the ethyl carbocation.

Which is more stable ethyl carbocation?

Benzyl carbocation is more stable than ethyl carbocation.

Which is more stable methyl carbocation or ethyl carbocation?

Ethyl carbocation is more stable than methyl carbocation as the ethyl carbocation is surrounded by 1 more carbon atom. Whereas there is no such carbon atom with methyl carbocation and is highly unstable.

Which is more stable an ethyl cation or propyl cation?

This analysis suggests that the 1-propyl cation would likely have a lower heat of formation than the ethyl cation. In other words, the 1-propyl cation would likely be more stable than the ethyl cation.

Is propyl more stable than isopropyl?

Bond-dissociation energy measurements tell us that isopropyl radical is 13 kJ/mol more stable than propyl.

Which is more stable ethyl or propyl?

Which is more stable propyl carbocation or ethyl carbocation? The greater number of alkyl groups with +I effect tend to increase the electron density on the positively charged carbon atom and dispers ethe charge on it.So propyl carbocation is more stable.

Is propyl a carbocation?

Because , +I effect of ethyl group is slightly higher than +I effect of methyl group . The stability order of carbocation is tertiary > secondary > primary . Now, both ethyl carbocation and n-propyl carbocation are primary carbocation .

Which carbocation is more stable one here?

Three main factors increase the stability of carbocations: Increasing the number of adjacent carbon atoms: methyl (least stable carbocation) < primary < secondary < tertiary (most stable carbocation)

Which is the most stable carbocation n propyl?

In triphenylmethyl cation, dispersal of positive charge increases with the increase in the number of benzene ring. Hence, it is the most stable carbonium ion.

Which is more stable 1-propyl or ethyl cation?

This analysis suggests that the 1-propyl cation would likely have a lower heat of formation than the ethyl cation. In other words, the 1-propyl cation would likely be more stable than the ethyl cation.

Which is more stable ethyl or methyl carbocation?

Inductive effect of ethyl will be higher than that of methyl so carbocation attached to ethyl (3 carbons in total) should be more stable. On the other hand 3 hyperconjugation structures can be drawn for the carbocation attached to methyl (2 carbons in total) and only 2 hyperconjugation structure for the other. Which effect wins?

Why is an allyl carbocation more stable than an alkyl carbocation?

Allylic carbocation is considered to be more stable than substituted alkyl carbocations because delocalization is associated with the resonance interaction between the positively charged carbon and the adjacent pie (π) bond. The allyl cation can be represented as a hybrid of two equivalent contributing structures.

What is the difference in stability between carbocations and free radicals?

The difference in stability between carbocations is much larger than between free radicals. The tert butyl radical is only 12 Kcal more stable than methyl free radical and hence depend upon the substrate with 66 – 72 Kcal more stable than the methyl cation.
