Paired electrons repel other pairs. Two Groups : Linear (CO 2 ) Three Groups : Trigonal Planar (BF 3 ) / Bent (SO 2 ) Four Groups : Tetrahedron (CH 4 ) / Pyramidal (NH 3 ) / Bent (H 2 O) Five Groups : Trigonal Bipyramid (PF 5 ) / See-Saw (SF 4 ) / T-Shaped (ClF 3 ) / Linear (XeF 2 ) Six Groups : Octahedral (SF 6 ) / Square Pyramidal (BrF 5 ) / Square Planar (XeF 4 )

Look for ELECTRON and MOLECULAR shape. Linear - 180° Trigonal Planar - 120° Bent – 105° 4 Bonds – 109.5° 3 Bonds - 107° 2 Bonds - 105° Double bond prevents turning of molecules.

Unformatted text preview: Isomer Same number of electrons and molecules but differently shaped. CIS - Same side. TRANS - Different sides Hybridization 2 Groups = sp 3 Groups = sp 2 4 Groups = sp 3 5 Groups = dsp 3 6 Groups = d 2 sp 3 Chiral = Mirror images (nonsuperimposable) / Look for four different thing / Look for CARBON PV = nRT P - ATM V - Liters n - Moles R Constant (.082) T - Kelvin STP = 0 Degrees CELSIUS (273K) & 1 ATM...
