point, unless it can hydrogen bond OH NH COOH. hydrogen bonding increases boiling point.
organic compounds tend to be correct answers combustible
neuclophile correct answers electron pair donor and hence a lewis base
structural isomers correct answers known as constitutional isomers
molecules that have a different bonding sequence
stereoisomers correct answers molecules that have the same bonding sequence but different
spatial orientation.
enantiomer-non-superimposable mirror images
, diastereomers-not mirror images-cis/trans
a pure sample of each enantiomers (100%s and 100%r) is said to be correct answers optically
active
each pure enantiomer rotates the plane of polarized light by a certain number of degrees
a 50:50 mixture of two enantiomers will NOT rotate the plane of polarized light is said to be
correct answers optically inactive
known as a racemic mixture
