Concept explainers
(a)
Interpretation:
State true or false for the following statement: Conformations have the same molecular formula and the same connectivity but differ in the three-dimensional arrangement of their atoms in space.
Concept Introduction:
Conformations are any three dimensional arrangement of atoms of a molecule arises due to rotation around the single bond.
(b)
Interpretation:
State true or false for the following statement:In all conformations of ethane, propane, butane, and higher
Concept Introduction:
Conformers are spatial three dimensional arrangement of atom of a molecule in space.
(c)
Interpretation:
State true or false for the following statement: In a cyclohexane ring, if an axial bond is above the plane of the ring on a particular carbon, axial bonds on the two adjacent carbon are below the plane of the ring.
Concept Introduction:
Axial is a position on a chair conformation of cyclohexane ring. It is extended from the ring parallel to the imaginary axis of the ring.
(d)
Interpretation:
State true or false for the following statement:In a cyclohexane ring, if an equatorial bond is above the plane of the ring on a particular carbon, equatorial bonds on the two adjacent carbons are below the plane of the ring.
Concept Introduction:
In chair conformation of cyclohexane equatorial position extends form the ring almost perpendicular to the imaginary axis of the ring.
(e)
Interpretation:
State true or false for the following statement: The more stable chair conformation of a cyclohexane ring has more substituent group in equatorial positions.
Concept Introduction:
A six-membered ring is more stable when the maximum number of substituent groups is equatorial.
