WebCorrect option is C) The iso structural pairs are [NF 3,H 3O +] and [NO 3−BF 3]. [NF 3,H 3O +] has tetrahedral geometry (pyramidal shape) due to sp 3 hybridization. The central atom contains 3 bonding domains and one lone pair of electron. The bond angle is less than 109.5 o [NO 3−BF 3] have trigonal planar geometry due to sp 2 hybridization. WebDec 29, 2016 · This will push the bond pairs N − H away from the central atom. So, the angle of H − N − H will decrease. N F X 3: Here F is more electronegative than N, so the …

WebSolution Verified by Toppr Correct option is A) Lone pair of electrons on nitrogen in (SiH 3) 3N are used up in pπ−dπ back bonding while in (CH 3) 3N such a pπ−dπ bonding is not possible due to absence of vacant d-orbitals in carbon. therefore (CH 3) 3N is more basic than (SiH 3) 3N. Solve any question of Coordination Compounds with:- esw truckingWeb2 y In (CH3)3 N has two lone pairs, hybridization is sp3.and pyramidal shape. But in (SiH3)3 N has two lone pairs, due to presence of vacant d orbital in Si atom, lone pair of N is shifted to vacant d orbital so it's hybridisation is sp2 with trigonal planar geometry.
