Step-by-step solution
CS 2 : S .. .. = C = S .. .. : = orientation of two electron pairs around carbon in linear. SO 2 : O .. .. = S .. = O .. .. : = orientation of three electron pairs is trigonal planar, but presence of one lone pair makes the structure bent. BF 3 : F .. .. − B | :F: − F .. .. : − NH 3 H − N .. | H − H − orientation of three electron pairs is trigonal planar, Since all electron pairs are bond pairs. Therefore, structure is trigonal planar. N H 3 H - N . . | H - H - orientation of four electron pairs is tetrahedral, bu
