GRADED A+.
⩥ the electronegative atom helps draw e- density away from the negatively
charged region, which has a stabilizing effect. Answer: Induction (ARIO)
⩥ sp = most stable with - charge
sp2 = in the middle
sp3 = least stable. Answer: Orbital (ARIO)
⩥ stronger acid. Answer: weaker base/stable base =
⩥ weaker, weaker. Answer: In equilibrium the _____ (more stable) acid is
paired with the ______ (more stable) base
⩥ favored side. Answer: the weaker side of the equilibrium =
⩥ steric strain. Answer: the interference between two bulky groups that
are so close together that their electron clouds experience a repulsion
⩥ torsional strain. Answer: Increased energy results when molecules
assume eclipsed or gauche staggered conformations
, ⩥ eclipsed conformation. Answer: a conformation about a carbon-carbon
single bond in which the atoms or groups on one carbon are as close as
possible to the atoms or groups on an adjacent carbon
⩥ gauge conformation. Answer: methyls are staggered in confromation
⩥ anti conformation. Answer: A type of staggered conformation in which
the two largest groups are antiperiplanar to each other; the most
energetically favorable conformation
⩥ equatorial (diagnal). Answer: are axial or equatorial more favored in
conformations?
⩥ enantiomers. Answer: isomers that are mirror images of each other
⩥ higher atomic number. Answer: in chiral centers the higher priority =
⩥ delocalization. Answer: the spreading of electron density over a larger
volume of space
⩥ the most significant resonance structure is the one with the most octets
filled. Answer: the most important rule of resonance structures
⩥ constitutional isomers. Answer: same molecular formula, different
connectivity
⩥ diastereomers. Answer: stereoisomers that are not mirror images
⩥ strong acid, protons can come off easier. Answer: lower pka =
