Question

Can someone please explain why this is non polar and not polar (based on molecule structure)? Thanks!

Answer 1

Polarity exists whenever there is a difference between electronegativity of atoms among which pair of electrons is shared. If one attracts the pair more strongly while the other attracts weakly then partial negative and positive poles are developed. In this case, electronegativity of both Carbon and Hydrogen is same, so they would attract shared pair of electrons with an equal force, hence no formation of negative and positive poles. So overall it is a non polar molecule.

Thank you!

No problem :)
