Question 1

Question
Chiral molecules are ...
Answer
  • mirror images & superimposable
  • mirror images & nonsuperimposable
  • not mirror images & superimposable
  • not mirror images & nonsuperimposable

Question 2

Question
Chirality is a [blank_start]property[blank_end] and enantiomerism is a [blank_start]relationship[blank_end]. A molecule is said to be [blank_start]chiral[blank_end] and its mirror images are called a pair of [blank_start]enantiomers[blank_end].
Answer
  • property
  • relationship
  • molecule
  • property
  • relationship
  • molecule
  • chiral
  • enantiomer
  • achiral
  • isomers
  • enantiomers
  • stereoisomers

Question 3

Question
For chirality, the central [blank_start]carbon[blank_end] atom must have [blank_start]four[blank_end] different groups attached.
Answer
  • carbon
  • four

Question 4

Question
For a molecule with n stereocentres, the maximum number of stereoisomers is
Answer
  • 2^2n
  • 2^(n+2)
  • 2^n
  • 2^(n-2)

Question 5

Question
Molecules with a plane of symmetry are chiral
Answer
  • True
  • False

Question 6

Question
A compound is called [blank_start]dextrorotatory[blank_end] (+) if it rotates the plane of light [blank_start]clockwise[blank_end]. A compound is called [blank_start]levorotatory[blank_end] (-) if it rotates the plane of light [blank_start]anticlockwise[blank_end].
Answer
  • dextrorotatory
  • clockwise
  • levorotatory
  • anticlockwise

Question 7

Question
The overall rotation of the plane of light through a racemic mixture is
Answer
  • 180 degrees clockwise
  • 180 degrees anticlockwise
  • 90 degrees clockwise than 90 degrees anticlockwise
  • no rotation

Question 8

Question
The [blank_start]Cahn Ingold Prelog System[blank_end] priorities is based on the [blank_start]atomic number[blank_end] and is used to assign R,S configuration to [blank_start]enantiomers[blank_end].
Answer
  • Cahn Ingold Prelog System
  • atomic number
  • enantiomers
