1.	Consider the following statements, I. Covalency of N is restricted to four. II. N cannot from `dpi-ppi` bond as the heavier element can. III. P and As cannot form `dpi-dpi` bond with transition elements when their compound like `P(C_(2)H_(5))_(3)" and "As(C_(6)H_(5))_(3)` act as ligands. Which of the above statements are true?A. I and IIB. II and IIIC. I and IIID. All of these
Answer» Correct Answer - A P and As from `dpi-dpi` bond with transition elemnts when their compounds like `P(C_(2)H_(5))` and `As (C_(6)H_(5))` act as lingands.
