Question 3: In his pioneering work, ________ was
able to isolate the isomers of tartaric acid because they crystallize
from solution as crystals each with a different symmetry.
Question 4: In ________, an
enantiomer is one of two stereoisomers that are
mirror images of
each other that are "non-superposable" (not identical), much as
one's left and right hands are "the same" but
opposite.
Question 5: Enantiomers have, when present in a symmetric environment,
identical chemical and physical properties except for their ability
to rotate plane-________ (+/-) by equal amounts but
in opposite directions.
Question 6: A mixture of equal parts of an optically
active isomer and its enantiomer is termed racemic and has a net
rotation of plane-________ of
zero.
