Aldehyde Chemical Structure

October 25, 2025 Harsh Singh Rajput

1. Identification Summary Aldehyde is a carbonyl functional group in which the carbonyl carbon is bonded to one hydrogen and one carbon (R–CHO). It is a terminal, sp², trigonal-planar carbonyl that is strongly electrophilic; hallmark spectroscopic features include a C=O IR band ~1720–1740 cm⁻¹ (lower with conjugation) and a diagnostic aldehydic C–H doublet near ~2720/2820 … Read more

Alcohol functional group (hydroxyl), generic 2D structure R–OH with hydrogen bonding concept

1. Identification Summary Alcohol (functional group) denotes an sp³ carbon bearing a hydroxyl (–OH) substituent: general formula R–OH. Hallmarks: hydrogen bonding, moderate nucleophilicity of the oxygen lone pairs, weak Brønsted acidity (pKₐ ~15–19), and formation of derivatives (ethers, esters, sulfonates). Brand Names Not applicable. Name Alcohol (hydroxyl functional group) Background Classified by substitution at the … Read more
