Which one is more stable and why?

(A) is more stable than (B) as the C=O. group will exist as C-O group with a partial positive charge on carbon and slight negative charge on oxygen and hence the partial positive charge on carbon is stabilized by +I effect of methyl group on( A).

Which form is more stable?

Complete answer: Graphite is thermodynamically the most stable form of carbon. Its standard enthalpy of formation is thus taken as zero. Let us see why it is more stable than all the other given allotropes of carbon.

Which is more stable O or O?

R- is a better nucleophile in general due to the very high negative charge density on Carbon atom which is far less stable than on O atom . ( Remember O is the second most electronegative atom , on it , negative charge is quite stable ) .

Which is more stable ch3ch2+ or ch3ch2ch2+?

both are primary but. the former one has a bulkier alkyl group and hence more inductive effect. and the latter one has more no of alpha hydrogen and hence more no of hyperconjugative structures..

What is another meaning of stable?

Some common synonyms of stable are durable, lasting, and permanent. While all these words mean “enduring for so long as to seem fixed or established,” stable implies lastingness because of resistance to being overturned or displaced.

Which of these Tautomerism is more stable?

alpha-hydrogen in it. This alpha-hydrogen is shifted or migrated to the nitrogen. because the latter one contains a carbon- nitrogen double bond which is very stable. So, imine is more stable than enamine form.

Which is more stable O2NCH2CH2O?

By withdrawing the electrons toward it, the NO2 group decreases the negative charge on the compound, thereby stabilising it. 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–.

Which ion is more stable Fe3+ or Fe2+?

Fe3+ is more stable than Fe2+. In Fe3+ ions, there are five 3d half-filled orbitals and is more symmetrical than Fe2+. Whereas in Fe2+ ion there are four 3d half-filled orbitals and one orbital is filled.

Which is the most stable carbonium ion?

So, the most stable carbonium ion among the above given molecules is (C6H5)3 – + C.

Which is the most stable Carbanion?

Note: Remember primary carbanion and methyl carbanion are the most stable carbanions.

What is stable example?

The definition of stable is something steady that is not prone to change, someone who is level headed and who isn’t subject to wild swings of emotion. An example of stable is a product that has a steady and unchanging price. An example of stable is a person who has a good handle on her life and her emotions.

Which is the best definition of the word stable?

Learner’s definition of STABLE [also more stable; most stable] 1 a : in a good state or condition that is not easily changed or likely to change

Which is the most stable type of kayak?

Most modern kayaks are very stable for their intended use. Fishing kayaks are very stable platforms for fishing. Recreational kayaks are also stable for the casual enjoyment of paddling. And ocean and touring kayaks, on the ocean and cutting through the water, are remarkably stable kayaks.

Which is more stable an even number of protons or neutrons?

An even number of protons or neutrons is more stable (higher binding energy) because of pairing effects, so even-even nuclides are much more stable than odd-odd. One effect is that there are few stable odd-odd nuclides: in fact only five are stable, with another four having half-lives longer than a billion years.

Which is more stable, Fe3 + or Mn2 +?

Both Fe3+ and Mn2+ because the electron configuration of these two ions has 5 electrons in 3d orbital (half filled). ie Mn2+ : [Ar]3d5 and Fe3+: [Ar]3d5. Why is Iron+3 more stable than Iron+2? fe is 1s2 2s2 2p6 3s2 3p6 4s2 3d6.
