WebApr 10, 2024 · 1 INTRODUCTION. Aldehydes are reactive compounds and can undergo chemical transformations to numerous other functional groups. 1 The aldehyde is therefore an invaluable chemical multi-tool to make all sorts of products. 2 As final products, aldehydes find application in the flavour and fragrance sector, because they are often … WebSuch a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. The atom that loses the electrons becomes a positively charged ion ( cation ), while the one that gains them becomes a negatively charged ion ( anion ). A brief treatment of ionic bonds follows.
