Why is fulminate ion so unstable?
The fulminate ion is unstable because the least electronegative attracts an electron (negative charge) while the atom with a higher electronegativity lost an electron, which rarely happens and the atoms are at unfavorable states.
How do you know if a compound has resonance?
Because resonance structures are the same molecules, they must have: 1) The same molecular formulas. 2) The same total number of electrons (same overall charge). 3) The same atoms connected together.
What is resonance write resonance?
Resonance is a mental exercise and method within the Valence Bond Theory of bonding that describes the delocalization of electrons within molecules. It compares and contrasts two or more possible Lewis structures that can represent a particular molecule.
What is resonance in chemistry quizlet?
resonance. resonance. a condition in which more than one Lewis structure is needed to accurately portray a molecule.
What is fulminate ion?
The fulminate ion, CNO − , is a pseudohalic ion because its charge and reactivity are similar to those of the halogens. Due to the instability of the ion, fulminate salts are friction-sensitive explosives. The best known is mercury(II) fulminate, which has been used as a primary explosive in detonators.
Why is NCO more stable than CNO?
You’re right that it has to do with formal charge. The less formal charges a molecule has, the more stable it is.
What is hyper conjugation effect?
Hyperconjugation effect is a permanent effect in which localization of σ electrons of C-H bond of an alkyl group directly attached to an atom of the unsaturated system or to an atom with an unshared p orbital takes place.
Is CO2 resonance?
Carbon dioxide, or CO2 , has three resonance structures, out of which one is a major contributor. The CO2 molecule has a total of 16 valence electrons – 4 from carbon and 6 from each oxygen atom.
Is C or H more negatively charged?
(High charge density is destabilizing. Positive charge is best accommodated on atoms of low electronegativity, and negative charge on high electronegative atoms.)…Charge Distribution.

What fulminate means?
: to utter or send out with denunciation fulminate a decree. intransitive verb. : to send forth censures or invectives fulminating against government regulators— Mark Singer.
What is the meaning of the word fulminate?
1. To issue a thunderous verbal attack or denunciation: fulminated against political chicanery. 2. To explode or detonate. 1. To issue (a denunciation, for example) thunderously. 2. To cause to explode. n. An explosive salt of fulminic acid, especially fulminate of mercury.
What kind of ion is the fulminate ion?
Fulminates are chemical compounds which include the fulminate ion. The fulminate ion, CNO− is a pseudohalic ion, acting like a halogen with its charge and reactivity. Due to the instability of the ion, fulminate salts are friction-sensitive explosives.
Which is the best example of a fulminate salt?
Due to the instability of the ion, fulminate salts are friction-sensitive explosives. The best known is mercury(II) fulminate, which has been used as a primary explosive in detonators. Fulminates can be formed from metals, such as silver and mercury, dissolved in nitric acid and reacted with ethanol.
What kind of fulminate is used in a detonator?
Mercury fulminate is more often employed in the detonator, and is prepared from mercury, alcohol, and nitric acid. The most tremendous explosives refuse to explode unless some detonator like fulminate of mercury is set off first. Digest copper (in powder or filings) with fulminate of mercury or of silver, and a little water.
