Concept explainers
(a)
Interpretation:
The Lewis structure for cyclopropane having molecular formula C3 H6 is to be drawn.
Concept Introduction:
During the formation of a compound each atom tends to lose, gain or share enough electrons to achieve an electronic configuration having eight valence electrons. This rule is also known as octet rule. The number of electrons present in outermost shell of an atom which are available for bonding are known as valence electrons. For a molecule, total number of valence electrons will be sum of valence electrons of each atom present in the molecule.
A Lewis structure is representation of distribution of electrons on each atom of the molecule. Some of the electrons are shared by atoms to form bonds and some exist as lone pair which do not take part in bonding.
(b)
Interpretation:
Using VSEPR Theory, the geometry of each central atom present in given structure of Cyclopropane is to be identified.
Concept Introduction:
Bond angles in the molecules can be predicted by using valence shell electron pair repulsion (VSEPR) model. According to this model, the valence electrons of an atom are involved in the formation of single, double or triple bond. The valence electrons can also be unshared and exist as lone pair on atoms. The combination forms a negatively charged region of electron density around a nucleus. Since, like charges do not attract, the region of electron density around a nucleus spread out so that each atom is as far away from each other at different angles.
(c)
Interpretation:
Using VSEPR theory, the various relative bond angles associated with each central atom of the Cyclopropane molecule is to be determined.

(d)
Interpretation:
Observing the given the shape and size of the Cyclopropane ring, the bond angle for C−C−C is to be predicted.
Concept Introduction:
Bond angle of the molecules can be predicted by using valence shell electron pair repulsion (VSEPR) model.
(e)
Interpretation:
A proper explanation with reason is to be given, why cyclopropane is considerably less stable than other three-carbon compounds that do not contain a ring.
