Based on this information, determine the I-P-I bond angle, the Br-P-Br bond angle, and the I-P-Br bond polar depending upon the ape of the molecule. For a r atoms the molecular Enter the number of degrees of the I-P-I.

The geometry of PI3br2 is a trigonal bthe arragipyramid. the polarity and non polarity of the structure depends on the arrngement of the atoms.
1. In first case, Br atoms are opposite to each other in axial position and Iodine atoms are in equatorial positions, then the molecule is a non polar one. The I-P-I bond angle is 1200, Br-P-Br bond angle is 1800, I-P-Br is 900.
2. In second case if one bromine and one Iodine takes axial position, then the molecule becomes slightly polar due to assymetrical arrangement of atoms, but the bond angles very close to 90 and 1200, with slight distortion/
2. CH2Cl2 is a polar molecule, the C-Cl ponds are polar and the molecule got tetrahedral shape and the individual dipolemoments donot cancel with each other. its polarity index is 3.1. so structurally it is a polar molecule.
