Hyperconjugation
超共轭
The interaction of electrons in a sigma bond (usually C-H or C-C) with an adjacent empty or partially filled p-orbital or pi-orbital. 1 This interaction can stabilize molecules and influence their reactivity.
σ 键（通常是 C-H 或 C-C）中的电子与相邻的空或部分填充的 p 轨道或 π 轨道的相互作用。这种相互作用可以稳定分子并影响其反应性。(σ jiàn (tōng cháng shì C-H huò C-C) zhōng de diàn zǐ yǔ xiāng lín de kōng huò bù fèn tián chōng de p guǐ dào huò π guǐ dào de xiāng hù zuò yòng. zhè zhǒng xiāng hù zuò yòng kě yǐ wěn dìng fēn zǐ bìng yǐng xiǎng qí fǎn yìng xìng.)
About the IPA
The International Phonetic Alphabet is a standardized system of symbols used to represent the sounds of spoken language.
It helps linguists, language learners, and educators accurately describe pronunciation across languages.
Example: the word "hello" in British English is transcribed as /həˈləʊ/ in IPA.
