Which is the least stable in the following?
Be− is the least stable ion, Be (1s22s2) has stable electronic configuration, addition of electron decreases stability.
Which of the following is least stable carbonium ions?
-That’s why more is the alkyl group attached to the carbonium ion, more will be stability. -So, methyl will have the least stability because it lacks an alkyl group. Therefore, option A is the correct answer.
Which of the following is most stable free radical?
Therefore, the most stable free radical is benzyl free radical. Hence the correct option is (B).
Which one of the following ions is the most stable in aqueous solution?
Cr3+ ion is the most stable in aqueous solution on account of maximum crystal field stabilization energy.
Which of the following five membered ring is most resonance stabilized?
Explanation: Thiophene is most resonance stabilized five membered rings among above compounds. As thiophene has Sulphur and least electronegativity ring than nitrogen and oxygen in pyrrole and furan respectively.
Which of the following Carboanion is not resonance stabilized?
NO3−
Why is nitrogen so stable?
The dinitrogen molecule (N2) is an “unusually stable” compound, particularly because nitrogen forms a triple bond with itself. … The octet requires an atom to have 8 total electrons in order to have a full valence shell, therefore it needs to have a triple bond.
