How do you know when to draw resonance structures?
Resonance structures are used when a single Lewis structure cannot fully describe the bonding; the combination of possible resonance structures is defined as a resonance hybrid, which represents the overall delocalization of electrons within the molecule.
What are the rules for writing resonance structures?
(i) Each structure should be such as not to alter the position of atoms, i.e., the nuclei of the atoms in each structure must remain in fixed position. Only the arrangement of electrons may change. The bond angles and bond lengths should be closer to the real structure.
How many resonance structures does s2o?
Hint: Sulfur dioxide ($SO_2$) has two resonance structures which contribute equally to the overall hybrid structure of the molecule.
How do you replace H with D?
Due to the acidic nature of α hydrogens they can be exchanged with deuterium by reaction with D2O (heavy water). The process is accelerated by the addition of an acid or base; an excess of D2O is required. The end result is the complete exchange of all α hydrogens with deuterium.
What does exchanges with D2O mean?
This strategy is called D2O exchange or, more colloquially, the “D2O shake.” This exchange eliminates the OLH resonance (thus identifying it) and also eliminates any splitting between the a-protons and the OLH proton. The only splitting re- maining is then the splitting with any b-protons.
What does deuterium do in organic chemistry?
Deuterium adds to the alkenes and alkynes in the same manner as hydrogen does. Deuterium oxide is a deuterium version of water, in which the protium of the usual water molecule is replaced by deuterium.

Is NO2 bent or linear?
NO2 is a bent molecule; however, when you remove an electron from it, making it NO2+, the molecule becomes linear due to the loss of a lone electron. In NO2+, there is no repulsion taking place between the two O atoms and the lone electron on the central atom.
