  2. Chlorate - Wikipedia

    en.wikipedia.org/wiki/Chlorate

    The chlorate ion cannot be satisfactorily represented by just one Lewis structure, since all the Cl–O bonds are the same length (1.49 Å in potassium chlorate [1]), and the chlorine atom is hypervalent. Instead, it is often thought of as a hybrid of multiple resonance structures:

  3. Clar's rule - Wikipedia

    en.wikipedia.org/wiki/Clar's_rule

    Clar's rule states that for a benzenoid polycyclic aromatic hydrocarbon (i.e. one with only hexagonal rings), the resonance structure with the largest number of disjoint aromatic π-sextets is the most important to characterize its chemical and physical properties. Such a resonance structure is called a Clar structure. In other words, a ...

    en.wikipedia.org/wiki/ClO3

    ClO3 may refer to: The chlorate anion, Monochlorine trioxide, a hypothetical radical akin to chlorine dioxide; The empirical formula for dichlorine hexoxide / chloryl perchlorate; The perchloryl cation, +

  5. Resonance (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Resonance_(chemistry)

    Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.

  6. Trigonal pyramidal molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Trigonal_pyramidal...

    The nitrogen in ammonia has 5 valence electrons and bonds with three hydrogen atoms to complete the octet.This would result in the geometry of a regular tetrahedron with each bond angle equal to arccos(− ⁠ 1 / 3 ⁠) ≈ 109.5°.

  7. Mesomeric effect - Wikipedia

    en.wikipedia.org/wiki/Mesomeric_effect

    In chemistry, the mesomeric effect (or resonance effect) is a property of substituents or functional groups in a chemical compound.It is defined as the polarity produced in the molecule by the interaction of two pi bonds or between a pi bond and lone pair of electrons present on an adjacent atom. [1]

  8. Sodium chlorate - Wikipedia

    en.wikipedia.org/wiki/Sodium_chlorate

    Sodium chlorate is an inorganic compound with the chemical formula Na ClO 3.It is a white crystalline powder that is readily soluble in water. It is hygroscopic.It decomposes above 300 °C to release oxygen [4] and leaves sodium chloride.

  9. Chloric acid - Wikipedia

    en.wikipedia.org/wiki/Chloric_acid

    Chloric acid is thermodynamically unstable with respect to disproportionation.. Chloric acid is stable in cold aqueous solution up to a concentration of approximately 30%, and solution of up to 40% can be prepared by careful evaporation under reduced pressure.
