Answer:
Oxygen is more electronegative than carbon.
Explanation:
Electronegativity increases from left to right across the periodic table. Since oxygen is further right than carbon, it is more electronegative. Also, if you look at a chart of electronegativity, oxygen has an electronegativity of 3.44 while carbon has an electronegativity of 2.55.
So oxygen is more electronegative than carbon. Hope this helps.
