MCQ s OF CHEMICAL BONDING BY-SANJAY KUMAR(JAM CHEM)
AmoleculeXY2 contains two -bonds, two and one lone pair of electrons in valence shell of X. The arrangement of electron pairs around X is (a) square pyramidal (b) linear (c) trigonal planar (d) data insufficient. 1. -bonds 2. In ICl2, ICl2 and ICl , sum of the bond pairs and lone pairs on each iodine atom are respectively (a) 2, 2 and 4 (c) 4, 5 and 4 (b) (d) 2, 3 and 2 4,5 and 6
(c): Geometry of molecules depends only on sigma bonded electron pairs and lone pairs but not on t-bonded electron pairs. 1. 1- Cl Cl Cl C Cl
3. The pair of species with similar shape is (b) CF4, SF4 (d) PF5, IFs I3, NH3 (c) PbCl2, CO2 In which of the following, the central atom does not use sp' hybrid orbitals in its bonding? (a) NOS (b) H, (c) NH2 (d) CH4 4.
(a) (a): No. of hybrid orbitals for NOS [5 + 0-0+1]-3 .. Type of hybridization is sp2. 3. 4.
