Partial 1.25 / 2 pts Question 4 Methane, CH4, ammonia, NH3, and water, H20 all have Equal , areas of electron density around the central atom, so they all have different electron pair geometry. Due to the presence or absence of lone pairs these three molecules have varying molecular geometry and as a result, different polarity. Methane has no lone pairs, tetrahedral molecular geometry and is non polar Ammonia has 1 lone pair with trigonal pyramidal molecular geometry and is polar Water has two lone pairs, bent molecular geometry and is polar Hint: if a molecule has a lone pair on the a central atom, it is likely to be polar.....meaning there is an uneven distribution of charge. Your answers for d, f and h are either polar or nonpolar......
