How do you determine which carbocation is most stable?

The more stable the carbocation, the lower the activation energy for reaching that intermediate will be. The more substituted a carbocation is, the more stable it is. The carbocation bonded to three alkanes (tertiary carbocation) is the most stable, and thus the correct answer.

Which of the following is more stable CH3 CH2 or CH3 CH2 CH2?

CH3CH2CH2+ is more stable than (CH3)2CHCH2+ because it have more alpha hydrogen which shows more hyperconjugative effect.

Which is the most stable carbocation CH3 3C+?

tertiary carbocation
(CH3)3+C is a tertiary carbocation. A tertiary carbocation is the most stable carbocation due to the electron releasing effect of three methyl groups.

Which of the following is the most stable cation cf3ch2+?

F3C-CH2+ is more stable . Because of inductive effect being a distance effect . In F3C-CH2+ magnitude of +ve charge is less decrease on already +ve carbon atom so is more stable than just CF3+ carbocation. F3cch2+ is more stable than f3c+.

How do you know if an organic compound is stable?

Rules for estimating stability of resonance structures

1. The greater the number of covalent bonds, the greater the stability since more atoms will have complete octets.
2. The structure with the least number of formal charges is more stable.
3. The structure with the least separation of formal charge is more stable.

Which is more stable CH3 or CH2?

CH3-CH(+)-OCH3 is more stable than CH3-CH(+)-CH3 because the mesomeric effect of O atom stabilises the carbocation to a greater extent than the inductive effect if CH3 can. CH2=CH-CH2+ is more stable because it is conjugated and thus resonance stabilised.

Which is more stable CH3 or CH3 CH2?

Greater the number of alkyl groups attached to a positively charged carbon atom, the greater is the hyperconjugation interaction and +I effect of methyl group greater is the stabilisation of the cation. Thus, (CH3)3C+ is more stable than CH3CH2 + and + CH3.

Which of the following species is better stabilized and by which effect CH3 ch2 and CH3 CH CH3?

Increased localisation of the –ve charge on a Carbon atom makes the species unstable. Hence CH3CH2– is more stable than (CH3)2 CH– .

Which of the following is more stable and why CH3 3C+ and CH3 2ch+?

Which of the following carbocation is more stable CH2 F?

The answer is b. It is a tertiary carbocation. A tertiary carbocation is the most stable carbocation due to the electron releasing effect of three methyl groups.

Which of the following is a more stable cation?

(CH3)3C+3∘ carbonium ion is most stable.
