The second one is filled in but not correct

Answer 1

VSEPR theory is used to explain the shapes of the molecules. The shape of the molecules depends upon the electron present in the valence shell of the central atom. Consider O In ozone molecules, oxygen is the central atom and it is bonded with the other two oxygen atoms. Central atom of ozone has one lone pair and it geometry is bent. Due to the presence of lone pair on central atom, the ideal angle 1200 reduces to 1 16。 O-o-O angle of O, is <1209 .Consider the structure of SO 0 In SO, molecule, sulfur is the central atom, and it bonded with three-oxygen atoms. The shape of the So is trigonal planar. Therefore, the angle between oxygen-sulfur-oxygen is 120° O-S-O angle of SO, is 120

Consider the structure of OF In OF,molecule, oxygen is the central atom and which is bonded with two fluorine atoms. Central atom has two lone pair. The shape is tetrahedral, due to the presents of two lone pair angle reduced from 109.5° O-F-O angle of OF, is <109.5 . Consider the structure of BeCl, :CBeCI: In BeCI,molecule, beryllium is the central atom and it bonded with two chlorine atoms. The geometry of the BeCl,molecule is linear. Therefore, angle is 180

. Consider the structure of SOC, Cl CI In SOCI, molecule, sulfur is the central atom and it bonded with two chlorine and one oxygen atom. Central atom has one lone pair. The molecular geometry of SOCl, is trigonal pyramidal and bond angle between oxygen-sulfur-chlorine is less than 109.5°. CI-S-O angle of SOCI, is <109.5。 Consider the structure of methane In CH ,carbon is the central atom and it is bonded with four hydrogen atoms. The molecular geometry of the methane is tetrahedral. Therefore, the angle is 109.5° H-C-H angle of CH, is 1095
