Give a molecular formula for your product if it contains no oxygens. Give the molecular formulas if your product contains one and two oxygens (some may not be possible). The molecular formula for if my molecule does not have any oxygens is C6H6, if it has one oxygen it would be C7H6O, if it was two it would be C8H7O2. Calculate the index of hydrogen deficiency, and therefore the number of rings and/or p- bonds in your unknown for each of the molecular formulas in question 3. Show your calculation
