Newman projection - Study guides, Class notes & Summaries

Basicity rules - -strong base: unstable/reactive (ED groups) -weak base: stable (EW groups/more EN/bigger) Chair conformation - -more stable equitorial (slanted) -pointing up/pointing down=cis if both up -elimination: trans and diaxial Newman projection - -gauche: substituent groups adjacent to eachother -grab middle and turn to put in plane Enantiomers - -not superimposable mirror images -same besides stereochemistry Diastereomers - -mirror images but one stereocenter stays and...

Exp: Molecular Modeling - newman projection: staggered - newman projection: eclipsed - Newman Projection Conformations and their relative energies [draw a graph] - The gauche conformation of butane occurs when the dihedral angle between at the C1-C2 and C3-C4 is 60 degrees. There is sterric strain in the molecule due the proximity of the two methyl groups. Would the sterric strain in this molecule increase OR decrease C1-C2-C3 [and C2-C3-24] bond angle was increased to more than 109.5...

Lewis dot structure: steps Correct Answer 1. Find total # of valence electrons for all atoms in molecule 2. Use one pair of electrons to form one bond between each atom 3. Arrange remaining electrons around atoms to satisfy duet for H and octet for other atoms Exceptions to octet rule Correct Answer 1. B, Be: may have less than an octet 2. Atoms with an odd number of electrons 3. Atoms in the 3rd period or greater (with d orbitals available for hybridization) may have greater than an octe...
