d-orbitals
The d-orbital is shown below:
To draw a d orbital(‘dxy’):
1. Hold down the mouse button over the Orbital tool and drag to select the d-orbital tool from the palette.
2. Click an atom where the node of the orbital is to be attached.
To draw a d
z
2-orbital:
1. Hold down the mouse button over the Orbital tool and drag to select the d
z
2-orbital tool from the palette.
2. Click an atom where the node of the orbital will be attached.
Chemical symbols
You can move any attached chemical symbol (other than H-dot and H-dash) any distance from its related atom. The
available chemical symbols are:
Figure 9.3: Chemical symbols: A)Circle Plus; B)Plus; C)Radical cation; D)Lone pair; E)H-dot; F)Attachment point;
G)Polymer bead attachment point; H)Attachment point; I)Attachment point; J)H-dash; K)Radical; L)Radical anion;
M)Minus; N)Circle minus.
You can place unattached symbol anywhere and resize them.
H–dot and H–dash
To represent a hydrogen atom that is coming out of the plane toward you along the Z axis, use the H–dot symbol.
To represent a hydrogen atom that is directed backwards into the plane away from you along the Z axis, use the H–
dash symbol. To insert H–dots and H–dashes, click an atom.
Lone pair/diradical
Use the lone pair symbol to indicate a lone pair of electrons common in Lewis structures.
1. Hold down the mouse button over the Chemical Symbols tool and drag to select the lone pair from the palette.
2. Click and drag the atom to where you want the lone pair. The lone pair is offset from the atom at a fixed position.
