Although C2 is not a commonly encountered chemical species (carbon is more stable
as diamond, graphite, and the fullerenes described in Chapter 8), the acetylide ion,
C2 2, is well known, particularly in compounds w
Ligand Close Packing
a. LCP Model Uses the distances between outer atoms in molecules as a guide to molecular
b. Similar to VSEPR Approach but focuses primarily on the outer atoms rather than the central
c. In LCP model, li

Effects of Size
Up until now, we said that electronegativity and atomic size are related to each other.
a. The most electronegative are the smallest
b. Exceptions Some examples where the size and EN has the opposite effect.

Groups of low and high symmetry.
1. Determine whether the molecule belongs to a group of low or high symmetry.
a. Low symmetry
We have Identity C1 Symmetry.
Ex. H2C=CClBr Mirror plane with C8 Symmetry.
b. High Symm
The angle in H3C-C-CH3 angle is smaller and the H3C-C=CH2 angle is larger than 120 degrees
