How Do You Spell STERIC?

Pronunciation: [stˈɛɹɪk] (IPA)

Steric is a term in chemistry that refers to the three-dimensional arrangement of atoms in a molecule. The word is spelled with a hard "c" at the end, which is pronounced as /k/. This spelling is derived from the Greek word "stereos," which means solid or three-dimensional. The word steric is commonly used in discussions of chemical reactions and molecular interactions, particularly in the fields of organic chemistry and biochemistry. Its proper pronunciation is /ˈstɛrɪk/.

STERIC Meaning and Definition

1. Steric is an adjective used to describe or pertaining to the spatial arrangement or positioning of atoms or molecules in a three-dimensional space. It is derived from the word "steric hindrance," which refers to the resistance offered by bulky groups or atoms in a molecule to the free rotation or movement of other groups or atoms around them.

   In the context of chemistry, steric effects play a crucial role in determining the physical and chemical properties of molecules. The steric interactions between atoms or groups within a molecule can influence their reactivity, stability, and overall behavior. A steric hindrance caused by large substituents can hinder or block the approach of other reactants to the reaction site, resulting in altered reaction rates and selectivities. Similarly, steric factors can affect molecular conformation, as bulky groups tend to adopt specific orientations to minimize unfavorable interactions.

   Steric considerations are especially important in organic and biochemistry, where they can dictate the shape and function of complex molecules. For example, the steric hindrance between amino acid side chains in proteins determines their three-dimensional folding patterns and hence their biological activity. In drug design, steric factors are evaluated to ensure optimal binding of a drug molecule to its target receptor.

   Overall, the term "steric" describes the structural or spatial aspects of molecules that arise due to the size, shape, or orientation of atoms or groups. Understanding steric effects is integral to comprehending molecular behavior and has significant implications in various scientific and industrial fields.

Etymology of STERIC

The term "steric" has its origins in the Greek word "stereos", meaning "solid" or "three-dimensional". It is derived from the Indo-European root "ster", which means "stiff" or "rigid". The word "steric" is commonly used in the field of chemistry to describe the influence of spatial arrangements and interactions on molecular structures and reactions.
