1.	Compound (A) on reduction with LiAIH_4 gives a hydribe (P) containing 21.72% hydrogen along with other products.The one mole of hydride (P) and 2 moles of ammonia at higher temperature gives a compound (Q) which is known as inorganic benzene. (A) hydrolyses incompletely and forms a compound (R) and H_3BO_2 Which of the following statement is incorrect for the compound (A) ?
Answer» It has trigonal planar geometry The bond length between the central ATOM and the substituent atoms is shorter than the sum of the covalent radii. The coordination geometry AROUND central atom of compound (A) and N atom in 1:1 complex of (A) and `NH_3` is same. In compound (A) , there is `ppi-dpi` bonding Solution : There is `2p pi-2p pi` bonding `4BF_3(A)+3LiAIH_4overset("Ether")to2B_2H_6(P)+3LiAlF_4, B_2H_6 +3O_2 to _2O_3 + 3H_2O`+HEAT Molecular WEIGHT of compound (P)=21.76+6=27.76 % of H in compound (P) i.e., `B_2H_6=6/(27.76)xx100=21.72` `B_2H_6+NH_3 oversetDeltatoB_3N_3H_6` (INORGANIC benzene) +`H_2` 1:2
