Document Summary
Atoms joined by single bonds can rotate relatively freely with respect to one another. **if chemical structure drawn with just lines (no wedges or dotted lines) can"t say anything about steric chemistry. Sp3 hybridization at centres: tetrahedral: angle 109 usually forcing to have angles of 60o. Examples of bond-line formulas that include three-dimensional representations. To get enantiomer switch wedge and dashes of h and oh. Enantiomers don"t have different properties, besides how diffuse light sp3 hybridized carbon example w/ trigonal planar geometry example w/ linear geometry sp sp2 hybridized carbons. Everything alkenes do but better (twice as much) B/c of two pi bonds vs one in alkenes. Terminal alkyne = acidic (hydrogen at end) End up with alkynil ion =c - # of covalent bonds usually formed by some elements typically encountered in organic compounds. P: # bonds = 3 or 5: thus, c is tetravalent, o is divalent, h and halogens are monovalent.
