What is the sum of the oxidation states of all the carbon atoms present in a single molecule of benz — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

The molecular formula of benzaldehyde is $C_7H_6O$ . Let the sum of the oxidation states of all 7 carbon atoms be S. Hydrogen is +1 and Oxygen is -2. Therefore, $S + 6(+1) + 1(-2) = 0 \Rightarrow S + 4 = 0 \Rightarrow S = -4$ .
