What can Chem draw do?
ChemDraw Professional is a drawing tool that allows users to draw chemical structures and reactions as well as biological objects and pathways. Users can also use it to predict properties and spectra, convert chemical structures to IUPAC names, view 3D structures, etc.
How do you make a Molfile?
Molfile compression Compressed molfiles can be created by choosing Edit / Source , then Format / Compressed Molfile in MarvinSketch or MarvinView. If you cannot find the Edit menu, then click on the upper left arrow in MarvinSketch, right click or double click the compound in MarvinView.
What is Chem Bio Draw?
ChemBioDraw is a software package for drawing chemical structures and creating 3D visualizations of them. The drawing portion of the software package is available for both PCs and Macs.
How do you show resonance structures?
Resonance Hybrids Draw the Lewis Structure & Resonance for the molecule (using solid lines for bonds). Where there can be a double or triple bond, draw a dotted line (—–) for a bond. Draw only the lone pairs found in all resonance structures, do not include the lone pairs that are not on all of the resonance structures.
Is ChemSketch free?

Adding atom labels Select the text tool from the tools palette. With the text tool selected, move to the end of an existing bond. When you are pointing to the end of the bond, a black square will appear. Press and release the mouse button without moving the mouse. A text editing box will appear.
Does O3 show resonance?
Ozone, or O3, has two major structures of resonance that contribute equally to the molecule’s overall hybrid structure. All structures reflect the 18 valence electrons required-6 out of 3 bonds and 12 as lone pairs placed on the oxygen atoms.
How does resonance work chemistry?
Resonance is a mental exercise within the Valence Bond Theory of bonding that describes the delocalization of electrons within molecules. It involves constructing multiple Lewis structures that, when combined, represent the full electronic structure of the molecule.
When can resonance structures be written for a molecule?
You can write resonance structures for any compound or ion that contains one or more double or triple bonds.
