# How do you find the least stable carbocation?

But the carbocation on double or triple bond is least stable due to decreased inductive effect by the neighbouring double bond.

## How do you know which Carbanion is most stable?

An electron withdrawing group (such as nitro group) stabilises carbanion. −NO2 group is electron withdrawing by both −I effect and −R effect. Hence, (c) is the most stable.

## Which carbocation is most stable in the following?

A tertiary carbocation is the most stable carbocation due to the electron releasing effect of three methyl groups.

## Which carbocation is more stable and why?

Tertiary carbocations are more stable than secondary carbocations. Via an effect known as hyperconjugation. A neighbouring C-H bond will make it more stable by donating some of its electron density into a carbocation’s empty p-orbital.

## How do you determine stability order?

Therefore order of stability is: b>a>c.

## Which is the correct order of stability of carbocation?

The correct order for the carbocation stability is: III > I > II.

## How do you know if carbocation is stable?

Ernest Z. The three factors that determine carbocation stability are adjacent (1) multiple bonds; (2) lone pairs; and (3) carbon atoms. An adjacent π bond allows the positive charge to be delocalized by resonance. Thus, H2C=CHCH+2 is more stable than CH3CH2CH+2 .

## Which carbocation is more stable CH3 C or ch3ch2c?

Detailed Solution The correct answer is hyperconjugation. (CH3)2C is more stable than CH3CH2 due to hyperconjugation.

## How do you calculate stability in organic chemistry?

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 one of the following is the most stable carbocation CH3 ch2 CH3 CH3 3C CH3 to CH?

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 carbocation CH3CH2 CH3 CH3 3C CH3 2CH?

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 carbocation is more stable than CH3 ch2 ch2 ch2?

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

## Which of the following is the most stable carbocation 2 CH3 CH och3 4 CH3 CH CH3?

The most stable carbocation is t-alkyl carbocation because the order of stability of alkyl carbocation is t-alkyl >s-alkyl> p-alkyl *> CH3 carbocation.

## Which ion is most stable 2 C6H5 3C CH3 3C?

The order of stability of carbanion are (C6H5)3C^ – >C6H5CH2^ – > allyl > CH3^ – > (CH3)2CH^ –

## Which of the following is most stable carbocation CH3 CH2?

The most stable carbocation is (1) CH3 – CH2 (2) CH.

## Why CH3 3C is less stable than CH3 2CH?

(CH3)3C+ i.e 3° carbocation is more stable carbocation than 1° carbocation i.e CH3+ or CH3CH2+ because 3° carbocation has more hyper conjunction effect i.e it has 9 alpha hydrogen which is more stable but CH3+ has 0 aplha hydrogen thats why it is least stable carbocation and CH3CH2+ has 3 alpha hydrogen it is also less …

## Which is more stable CH3 3c+ CH3 2ch+?

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 is more stable CH3 3c+ or phch2+?

Why is (CH3)3C+ more stable carbocation than PhCH. This statement is wrong. Actually, is more stable than. This is because is resonance stabilised.

## Which of the following is more stable CH2 CH2?

CH2=CH-CH2+ is more stable because it is conjugated and thus resonance stabilised.

## Which is more stable CH3 or C2H5?

C2H5+ is more stable than CH3+.

## Which of the following is most stable cation a f3c ch2 B CH3 2ch+ C CH3 D cf3?

Hence structure (b) which is having nine sigma C−H bonds will be the most stable carbocation.

## Which is the more stable CH3 3C or CH3C H2?

CH33C+ has nine alpha hydrogens and has nine hyperconjugation structures while CH3C+H2has three alpha hydrogens and has three hyperconjugation structures therefore CH3 3C+ is more stable than CH3C+H2.
