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 In hydride (A) (select correct statement):

Answer» The central atom has trigonal PLANAR geometry All H-atom lie in the same plane All four terminal B-H bond lengths are equivalent but that of four bridging B-H bond lengths are not equivalent A three centre two -electrons bond (3c-2e) is formed by OVERLAP of an `sp^3` hybrid ORBITAL from each boron atom with the 1S orbital of HYDROGEN atom Solution :
