This    chapter is  vital   for understanding   all the reactions   you’ll  see in  the next    six chapters    of
this    book    (Chapters   5-10).  On  top of  that,   this    material    is  directly    tested  on  the MCAT    as  often
as  any other   topic   in  organic chemistry.  Make    sure    you know    all of  it!Introduction
Sitting down    to  MCAT    organic chemistry   problems    can be  overwhelming    at  first,  particularly    if  the
reactants   or  reagents    are new to  you.    The reactions   on  the page    may seem    like    stage   magic—fun   to
watch,  but controlled  by  forces  outside of  our knowledge.  The good    news,   however,    is  that    organic
chemistry   isn’t   magic—and   it  is  governed    by  sets    of  rules   that    make    understanding   what    will    happen
much    simpler.    In  this    chapter,    we  will    go  over    several of  the aspects that    determine   how a   complex
reaction    proceeds,   and take    a   brief   look    at  functional  group   reactivity. Then,   armed   with    this
knowledge,  we  lay out the simple, sequential  steps   that    we  can use to  determine   which   reactions
will    take    place.  Chapters    5   through 10  of  MCAT    Organic Chemistry   Review  focus   on  applications    of
these   principles  with    different   functional  groups, so  look    for patterns    between these   reactions   as
you continue    preparing   for Test    Day.    With    these   tools   in  hand,   we  can show    the MCAT    that    we  know
how the trick   is  done—it isn’t   magic.
