Question

What are the factors that do not govern the stability of a conformation in acyclic compounds?
a.) Torsional strain
b.) Angle strain
c.) Steric interactions
d.) Electrostatic forces of interaction

Answer 1

. The acyclic compounds are just opposite to the cyclic compounds because they do not form any ring like the cyclic compounds. Acyclic compounds are known as open chain compounds because of their linear structure.

Complete step by step answer:
The best example of an acyclic compound is alkanes. The acyclic compounds can be understood by using the straight chain or the branched chain compounds.
Torsional strain or the eclipsing strain is the increase in the potential energy due to the repulsion between the electrons in the bonds which do not share an atom.
Steric interactions are the non-bonding interactions which are responsible for the shape and reactivity of the ions and molecules. Steric effects along with the electronic effects and dictate the shape and reactivity of a molecule.
Electrostatic force of interaction is the attraction between the charges, the charge can be either positive or negative. It is the attractive force between the same charge species and the repulsive force between the different charge species.
Angle strain is a type of instability which only occurs in the cyclic compounds. The angle strain is mainly for the small rings, whose internal angles are substantially smaller than 109 degree centigrade.
So, the correct answer is “Option B”.

Note: Cyclic compounds are known as ring compounds. Cyclic compounds are those compounds in which one or more atoms are connected in a close ring. It is not compulsory that the size of the ring formed by the same compounds are always the same.
