why is cobaltocene unstable
Cobaltocene is Co(C5H5)2 where Co is sandwiched between two cyclopentyl rings. It has 19 valence electrons whereas other organotransition metal complexes have only 18. This one extra electron occupies an orbital that is antibonding with respect to Co-C bonds. This makes the Co-C distances longer. Due to this, the bonds can easily break and hence the molecule is unstable.
why enol is unstable? Why it tend to be unstable and isomerize to the keton form?
What is the least unstable sugar (ex. glucose, sucrose, etc.) and why?
why is a primary alkyl peroxy radical more exothermic (unstable) than a secondary?
Why is the diamond structure unstable with respect to the graphite structure at room ambient atmospheric pressure? Why is significant pressure required to form diamond crystals
15 pts) For the following transfer functions. explain why the responses will be stable (or unstable) and oscillatory (or non- oscillatory) to an impulse input. 2-1 a. H(s)-+9 s+2 s2 +2s +10 s+1 c. H(s)-
(20 10Ne) (72 37Rb) (16 8O) (11 5B) why isotope of Rb is most unstable? is there any general rule to make a decision between Rb and B in this question?
2) Why do you think we add an excess of the relatively unstable hydrogen peroxide or hydrobromic acid to the reaction? Group of answer choices A) Some of the reagent will evaporate due to the heat of reaction B) Some of the reagent will be voted out of the flask. C) Some of the reagent will inherently not be reactive. D) Some of the reagent will be lost to decomposition without having a chance to react.

What happens to isotopes that are unstable? What are the mechanisms by which unstable isotopes may decay into stable isotopes? How may these natural processes be used by chemists to make measurements in the medical, environmental or analytical chemical fields?
