Noun
/pærə ˈpɒzɪʃən/
The term "para-position" is primarily used in organic chemistry to describe a specific arrangement of substituents on an aromatic ring. When two substituents are located on a benzene ring opposite to one another (1,4-positions), they are said to be in the para-position. This term is not commonly used outside of scientific and academic contexts, making it more frequent in written rather than oral speech.
The compound has a hydroxyl group in the para-position, resulting in increased reactivity.
(El compuesto tiene un grupo hidroxilo en la posición para, lo que resulta en una reactividad aumentada.)
Positioning the substituents in the para-position is crucial for the desired chemical properties.
(Colocar los sustituyentes en la posición para es crucial para las propiedades químicas deseadas.)
In the para-position, the bond angle influences the stability of the molecule.
(En la posición para, el ángulo de enlace influye en la estabilidad de la molécula.)
While "para-position" itself is not frequently used in idiomatic expressions, it is important in the context of chemistry and can be referenced when discussing methods of synthesis or arrangement of molecular structures. Here are a few sentences using related idiomatic contexts:
Understanding the para-position in aromatic compounds is a key to mastering organic chemistry.
(Entender la posición para en compuestos aromáticos es clave para dominar la química orgánica.)
The effects of para-positioning in drug design can lead to breakthrough discoveries.
(Los efectos del posicionamiento para en el diseño de fármacos pueden llevar a descubrimientos revolucionarios.)
In pharmaceuticals, achieving the right para-position can make or break a compound's effectiveness.
(En farmacéuticos, lograr la posición para adecuada puede hacer o deshacer la eficacia de un compuesto.)
The term "para-" originates from the Greek word "para," meaning "beside" or "alongside." In the context of chemistry, it is used to denote the positioning of substituents in relation to each other on a cyclic structure, specifically indicating that they are located across from one another on the benzene ring.
Synonyms: - para-substituted (in specific contexts)
Antonyms: - ortho-position (1,2-position) - meta-position (1,3-position)
