Hydrocarbons 1 Question 2
2. Which of these factors does not govern the stability of a conformation in acyclic compounds? (2019 Main, 10 April II)
(a) Electrostatic forces of interaction
(b) Torsional strain
(c) Angle strain
(d) Steric interactions
Show Answer
Solution:
- The four types of strains $v i z$ (a) electrostatic force of attraction, (b) torsional strain, (c) angle strain, (d) steric stain, are responsible for the stability or energy barriers of conformers. In cyclic compounds, all types of strains may be present.
| Compound | Type of strains/forces |

In a cyclic or open-chain compounds, angle strain (c) is absent. e.g.
