1.	Which of the following is not a correct statement ?A. Every `AB_(2)` molecule does in fact has square pyramid structure.B. Maltiple bonds are always shorter then cotreponding single bonds.C. The electron deficient molecule can act as Lewis acids.D. The canonical structure have no real existence.
Answer» Correct Answer - a `IF_(3)` is squre pyramid `(sp^(3) d^(2)- "hybridization in" 1)` in `PCI_(3)` is trigonaal bipyramid (`sp^(3)` d-hybridazition in P).
