Why is CH2 too unstable to form?

Originally Answered: Why CH2=CH+ is unstable? You might be asking because it would be and intermediate in a reaction. It is unstable because it is a carbocation. It violates the octet rule hence is unstable, it has only 6 valence electrons rather than having 8.

Why CH2 CH CH2 is more stable than CH3 CH2 CH2?

CH2=CH-CH2+ has a double bond. This double bond electrons will participate in resonance due to which there would be two contributing structures to the stability of this molecule. On the other hand, CH3-CH2- CH2+ has no such structure. Therefore CH2=CH2-CH2+ will be more stable than CH3-CH2-CH2+.

Which has maximum stability CH2 CH CH2?

Correct Option- i Conjugated alkadiene CH2 =CH—CH =CH2 Explanation-i Due to resonance conjugated alkadiene is maximum stable. Isolated is more stable than cumulated alkadiene due to H-effect .

Which is more stable CH4 or CH2?

You could think of the reason CH4 forms is that CH4 would allow the carbon to have a full octet and would be more stable than CH2 in that sense, and in order to have CH4, there would be hybridization.

Why is CH4 not CH2?

Why then isn’t methane CH2? When bonds are formed, energy is released and the system becomes more stable. If carbon forms 4 bonds rather than 2, twice as much energy is released and so the resulting molecule becomes even more stable.

Which is more stable and why CH3?

(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 of the following is more stable CH3CH2 or CH3 CH2 CH2?

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

Which is more stable CH3 ch2 ch2?

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

Which of the two CH3 CH CH3 and CH3 CH2 CH2 is expected to be more stable and why?

On the other hand, ethyl group is an electron-releasing group. Hence, the ethyl group shows +I effect. This increases the negative charge on the compound, thereby destabilising it. Hence, O2NCH2CH2O– is expected to be more stable than CH3CH2O–.

Why is CH4 stable?

Carbon (4 electrons in the valence shell) combines with four hydrogen atoms to form a stable covalent compound where it shares 8 electrons, while each hydrogen shares 2. Thus it needs to combine with 4 hydrogen atoms to form a stable compound called methane (CH4) as shown above.

Is ethene more acidic than NH3?

The electronegativity of the carbon increases to a great extent when and turns out to be 3.2, which is greater than the electronegativity of nitrogen which is 3.04. Hence the hydrogen of ethyne is more acidic than that of NH3.
