chiral - ANSWER-A molecule that is not superimposable on its mirror image.
Typically a carbon atom bonded to four different atoms or molecules.
achiral - ANSWER-three different substituents often have plane of symmetry. and
rotation of 180 will allow molecule to be superimposed on mirror image
chiral. - ANSWER-Each of our hands is
Isomers - ANSWER-compounds with the same formula but different structure
Constitutional isomers - ANSWER-compounds with the same molecular formula
but a different connectivity of their atoms
Stereoisomers - ANSWER-molecules that have the same structural formulas and
bonding patterns but different arrangements of atoms in space, molecules that
have the same structural formulas and bonding patterns but different
arrangements of atoms in space
Constitutional isomers - ANSWER-what type of isomer
stereochemistry - ANSWER-the study of the three-dimensional structure of
molecules
Enantiomers - ANSWER-molecules that are mirror images of each other
, Diastereomers - ANSWER-non mirror image of configurational isomers. cis and
trans alkenes are them. possible when a molecule has two or more stereogenic
centers that differ at some but not alll of the centers. they require multiple chiral
centers.
Diastereomers - ANSWER-Diastereomers or Enantiomers
True - ANSWER-Enantiomers occur only with compounds whose molecules are
chiral.
5.1 (a) Achiral
(b) Achiral
(c) Chiral
(d) Chiral
(e) Chiral
(f) Chiral
g) Chiral
(h) Achiral - ANSWER-Classify each of the following objects as to whether it is
chiral or achiral:
(a) A screwdriver
(b) A baseball bat
(c) A golf club
(d) A tennis shoe
(e) An ear
(f) A woodscrew
(g) A car
(h) A hammer
One way (but not the only way) is to recognize that a pair of enantiomers is
always possible for molecules that contain a single tetrahedral atom with four
different groups attached to it. - ANSWER-What structural feature can we use to
know when to expect the possible existence of a pair
of enantiomers?
chirality centers - ANSWER-carbon atom bonded to four different groups
tip - ANSWER-The presence of a single chirality
center in a molecule guarantees that the molecule is chiral and that enantiomeric
forms are possible.
