Free radical
Electrophilic addition
4.
Enantiomers differ in:
boiling point
molar mass
density
direction of rotation of plane-polarised light
5.
The shape around the carbocation in SN1 is:
tetrahedral
trigonal planar
linear
pyramidal
6.
Which instrument measures optical rotation?
Mass spectrometer
pH meter
Polarimeter
Colorimeter
7.
Which statement best describes Enantiomer?
One of a pair of optical isomers.
An equimolar mixture of two enantiomers, which is optically inactive because the rotations cancel.
A positively charged carbon intermediate with a trigonal planar shape.
Molecules with the same structural formula but a different arrangement of atoms in space.
8.
Which statement best describes Chiral centre?
A carbon atom bonded to four different atoms or groups.
A positively charged carbon intermediate with a trigonal planar shape.
An equimolar mixture of two enantiomers, which is optically inactive because the rotations cancel.
One of a pair of optical isomers.
9.
Which statement best describes Stereoisomers?
Light whose vibrations occur in a single plane.
An equimolar mixture of two enantiomers, which is optically inactive because the rotations cancel.
Molecules with the same structural formula but a different arrangement of atoms in space.
Stereoisomers that are non-superimposable mirror images of each other (enantiomers).
10.
Which statement best describes Carbocation?
Stereoisomers that are non-superimposable mirror images of each other (enantiomers).
An instrument used to measure the angle through which a sample rotates plane-polarised light.
An equimolar mixture of two enantiomers, which is optically inactive because the rotations cancel.
A positively charged carbon intermediate with a trigonal planar shape.
