– There are exceptions to the “contains carbon” rule for inorganic compounds, which include oxides of carbon (CO, CO₂), carbonates, bicarbonates, cyanides, cyanates, thiocyanates, carbides, and elemental carbon forms.
– Marsh gas is Methane (CH₄), a simple hydrocarbon (alkane) and a classic organic compound.
– Urea ((NH₂)₂CO) contains a carbonyl group (C=O) and amine groups (NH₂). It is an organic compound, specifically an amide.
– Cane sugar is Sucrose (C₁₂H₂₂O₁₁), a disaccharide carbohydrate, which is a large class of organic compounds.
– Therefore, Ammonium cyanate is the only compound in the list that is considered inorganic.
