1.	Elements X, Y and Z have 4, 5 and 7 valence electrons respectively, (a) Write the molecular formula of the compounds formed by these elements individually with hydrogen. (b) Which of these compounds will have the highest dipole moment ?
Answer» SOLUTION : Z has seven electrons in its VALENCE shell. It is the most electronegative element. THEREFORE, HZ will have the highest DIPOLE moment.
