Because of the two lone pairs there are therefore 6 lone pair-bond pair repulsions. there are 5 electron pairs around the central I atom which according to VSEPR theory form a trigonal bipyramid. In chemistry, a lone pair refers to a pair of valence electrons that are not shared with another atom in a covalent bond[1] and is sometimes called an unshared pair or non-bonding pair. With all 4 elements (the 3 covalent bonds plus the lone pair) you would think it was Tetrahedral, with 109.5 degrees between them, but because the lone pair is there, it pushes the other bonding electrons closer together and thus you have a smaller angle of 107.5 degrees and the different shape.
