Expressing resonance when drawing Lewis structures may be done either by drawing each of the possible resonance forms and placing double-headed arrows between them or by using dashed lines to represent the partial bonds (although the latter is a good representation of the resonance hybrid which is not, formally speaking, a Lewis structure).
Methanol and its vapours are flammable. Moderately toxic for small animals – Highly toxic to large animals and humans (in high concentrations) – May be fatal/lethal or cause blindness and damage to the liver, kidneys, and heart if swallowed – Toxicity effects from repeated over exposure have an accumulative effect on the central nervous system, especially the optic nerve – Symptoms may ...
Draw the structure in your molecule editor (ideally change the settings to give a molecule twice the size as the JACS standard or change the size to 200% before next step), and save it as an Encapsulated PostScript file (.eps) - many of the Apple print drivers (an Apple printer is not required) that print to a PostScript printer can be set to ...
Seasonal flu activity is elevated across most of the country, according to the latest reports from the Centers for Disease Control and Prevention, and experts say this is expected to continue for ...
So, after drawing the bonds with C2, before drawing the bonds with C3 the molecule must be rotated in space by 180° about its vertical axis. Further similar rotations may be needed to complete the drawing. This implies that in most cases a Fischer projection is not an accurate representation of the actual 3D configuration of a molecule.
