Portaal Chemie

Naftaleen is 'n organiese verbinding met formule C10H8.

Dit is die eenvoudigste polisikliese aromatiese koolwaterstof en is 'n wit kristallyne vaste stof met 'n kenmerkende geur wat waarneembaar is in konsentrasies so laag as 0,08 dpm per massa.[2] As 'n aromatiese koolwaterstof, bestaan die struktuur van naftaleen uit 'n versmelte paar benseenringe.

Dit is veral bekend as die hoofbestanddeel van tradisionele motballe.
