What is polar
Asked by | 17th Mar, 2008, 01:20: PM
covalent bond is formed by sharing of electron pair btw two atoms of same or diff element .
if it is formed btw atom of diff element then atms involved will hv diff electronegativity values
so shared pair of electrom will b slightly displaced towards more electronegative atom giving it partially negative charge n partial positive charge to the other involved atom .so giving polar character to covalent bond
C–H C is partially negative n H is partialy positive as C is more electronegative then H
polarity may also arise due to other reasons in a covalent bond as due to lone pair effect of O in water ,

- Is fullerne a good conductor of electricity? Some people said that, "its structure resembles to that of the graphite thus it is good conductor of electricity." But, Some said that, "Fullerne do not have layered structure like graphit and that is why free electrons do not jump and move easily . Thus, Fullerene is a bad conductor of electricity/ insulator. " So I am confused which is correct. Please solve my doubt.
