B is ur answer bcz in A and D there are no poles bcz similar elements on both sides of the compound cancel the polarity of the compound. with those options eliminated, C has O and Cl at the two oppoite sides while B has Cl and H. the greater difference of electronegativity or polraity is between H and Cl so B is the sure answer.http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Chemistry (9701)/9701_w09_qp_11.pdf
Can anyone please explain, question number 5 of the above paper.
Regards!
