I have not taken Chemistry in a year but I remember that if you look at a periodic table there are certain sections for polar and non polar elements. I dont know if you have learned that yet
If you're studying electronegativity, somewhere in your textbook or lectures they probably will have shown you a periodic table with electronegativities on it. Find the difference between the two electronegativities of the elements in each bond and order them. Hope this helps!
