Aldehydes are organic compounds containing the –CHO (formyl) functional group, where a carbonyl carbon is bonded to at least one hydrogen atom. Many lower aldehydes are liquids or gases, but higher aromatic or substituted aldehydes exist as crystalline solids. Aldehyde crystals are generally colorless to pale solids with a distinct characteristic odor. They show polarity due to the carbonyl group and have lower melting points compared to corresponding carboxylic acids because they lack strong intermolecular hydrogen bonding. Aldehydes are chemically reactive and readily undergo oxidation to form carboxylic acids. They give positive Tollens’ and Fehling’s tests, which help in their identification. #challenge #education #viral #chemistry #vuralvideo #cbse #cbseclass12 #ppw #organic #reels
