Definitions:

Angle Strain

The increase in energy associated with a molecule when bond angles deviate from their ideal values, often observed in cyclic compounds.

Torsional Strain

A type of strain in molecules caused by rotating around a bond, due to the repulsion between electrons in non-bonded atoms.

Cyclopropane

A cycloalkane composed of three carbon atoms linked to each other to form a ring, used as an anesthetic.

Newman Projection

A method of visualizing the conformation of a chemical compound through a projection along a bond to show the spatial orientation of substituent groups.
