Sp³ hybridization is important in describing the bonding in: CCl₄ NH₄⁺ H₃O⁺ AgCl Question 1 of 10Question 2 of 10 2. In the formulation of N₂⁺ from N₂, the electron is removed from π*₂p orbital π₂p orbital σ px orbital σ pz orbital Question 2 of 10Question 3 of 10 3. The geometry of PF₅ molecules is Planar Trigonal bipyramidal Tetrahederal Square planar Question 3 of 10Question 4 of 10 4. Which is not characteristic of π bond? π bond is formed when a sigma bond already exist π bond are formed from hybrid sp orbitals π bond may be formed by the overlapping of p and /or d-orbitals. π bond results from lateral overlap of atomic orbitals. Question 4 of 10Question 5 of 10 5. The percentage of ionic character of bond between two atoms is calculated from the difference between their Ionization energies Electron negativities Electron affinities Ionic Question 5 of 10Question 6 of 10 6. Greater the dipole moment Greater is the ionic nature None Lesser is the polarity Smaller is the ionic nature Question 6 of 10Question 7 of 10 7. The bond energies of F₂, Cl₂, Br₂, and I₂ are 37, 58, 46 and 36k Cals, respectively. The strongest bond formed is in: I₂ Cl₂ Br₂ F₂ Question 7 of 10Question 8 of 10 8. According to VESPR theory, the most probable shape of the molecule having 4 electron pairs around the central atom is Linear Hexagonal Octahedral Tetragonal Question 8 of 10Question 9 of 10 9. A diatomic molecule has a dipole moment of 1.2 D. If its bond distance is 1.0A°. What fraction of electric change ‘e’ exsits on each atom? 18% of e 30% of e25% of e 12% of e Question 9 of 10Question 10 of 10 10. H–O–H bond angle in H₂O is 104.5° and not 109.28° because of High electronegativity of oxygen Lone pair – bond pair repulsion Bond pair – bond pair repulsion Lone pair – lone pair repulsion Question 10 of 10 Loading...
