Which of the following is NOT a carbon containing compound? Carbon Dioxide (CO2) Calcium Carbonate (CaCO3) Water (H2O) Methane (CH4)

The correct answer is Water .Explanation:Carbon-containing compounds are compounds that contain the element carbon. Among the options provided:1. Carbon Dioxide is a carbon-containing compound, as it contains one carbon atom bonded to two oxygen atoms.2. Calcium Carbonate is a carbon-containing compound, as it contains one carbonate ion , which contains one carbon atom bonded to three oxygen atoms.3. Water is not a carbon-containing compound, as it only contains hydrogen and oxygen atoms.4. Methane is a carbon-containing compound, as it contains one carbon atom bonded to four hydrogen atoms.Therefore, the compound that is NOT a carbon-containing compound is Water .
