Answer 1

Q-6. If the orbitals of two atoms overlap and interact with constructive interference, the resulting increase in wave density results in a(n): a onding molecular orbital b. antibonding molecular orbital constructive inference takes place to form bonding molecular orbitals which has mor electron density than individual atomic orbitals c. free radical formation d. cation formation material. Q-7. "Doping" pure silicon with gallium results in a(n) /p-type doping of Si with IIA group elements, b. n-type Gallium produces p-type semiconductor c. S-type d. d-type Q-8. You are likely to observe H-bonding in which of the following molecules? a. NaF H-bonding is formed only when hyd rogen is connectedd to more electronegative O,F, N atoms only b. C2H4F2 c. Na20 d/HF Q-9. The dopant atoms in an n-type semiconductor have more b. less electrons than the host material. n-type semi conductors are doped with VA group elements which has more electrons than the host c. equal d. zero material Q-10. Elemental iodine (12) is a solid at room tem among different 12 molecules in the solid? A) London dispersion forces B) dipole-dipole rejections C) ionic-dipole interactions D) covalent-ionic interactions E) dipole-dipole attractions ure. What is the major attractive force that exists
