A classmate of yours is convinced that he knows everythingabout electronegativity. (a) In the case of atoms X and Y havingdifferent electronegativities, he says, the diatomic moleculeX¬Y must be polar. Is your classmate correct? (b) Yourclassmate says that the farther the two atoms are apart in abond, the larger the dipole moment will be. Is your classmatecorrect?
