31. Which combination of the compounds and their geometry are correct h) CIF, - V-shaped e) CIF, - Tshaped OB. a HeCl, - linoar 24. Which of the following havea bond angle smaller than tetrahodral hond b) Sil, e) NH, d) 1,0 25 In which of the fellowing molecules, vacant orbitals take part in hybridization al BH, HN ( h) AL,C, e) H,PO, 20. Which of the following molecules have (-0-0-) bond, ie., peroxide bond? a) H,8,0 b) H,S,0, c) H,SO, 4) H,5,0, Linked Comprehension Type Questions Passage-: Wihen half-filled valence orbital of one atom overlaps with falf-filled valence orbital of hes covalent bond is formed. Head on or axial overlap leads to the formation of sigma bond. Svbevi latral overlap of atomic orbitals (p) give rise to the formation of t -bond. Similarly side wse ovth berween d- orbitals can lead to the formation of &- bond. In case of n-bond, the proteblit finding the shared electron cloud is zero along the line joining two nuclei while the protsbitey finding the shared electroi cloud is maximum along the inter nuclear axis. 27. Ifx-axis is the internuclear axis then which of the following combination will resuli formation of t-bond? d) s+s b) 2p, + 2p, 28. The strength af bonds by s-s, p-p, s-p overlap is in the order (exclading 1s): b) s-s < p-p < 5-p a)s - 2p. c) 2p, + 2p. a) S-s < s-p < p-p c) s-p< s-s p-p d) p-p <s4<9 29. if the intermuclear axis is x-axis, which of the following will not give non bonding combinating p and s dand p, y d andp, sands b) c) d) Pessage-l : Most of the polyatomic molecules except a few such as CO, and CS, which are linear or angule with a bond angle generally somewhat greater than 90", A bond angle is defined as the angle berwe the direction of two cavalent bonds. Since the atoms in molecules are in constant motion respect to each other, they are not expected to have a fixed value of bond angle. 0. Which of the foilowing having highest bond angle ? a) H.S b) HSD c) H,Se 1. In P d) All have same bond angle molecule phosphorus atoms are tetrahedrally arranged. The bond angle P-P-P in the is a) 108° b) 120° d) 180° 2. Which of the following hybridisation may have more than one type of bond angle? c) 60 a) sp by sp 38 c) sp'd d) sp'd 31.
