Metal Oxide SrO BaO CsF RbF -3217 -3029 -744 -785 A) The magnitude of the lattice energy is directly proportional to the charges of the ions B) The magnitude of the lattice energy is inversely proportional to the charges of the C) The magnitude of the lattice energy is inversely proportional to the charges of the D) The magnitude of the lattice energy is directly proportional to the charges of the ions E) The magnitude of the lattice energy is directly proportional to the charges of the ions involved and also directly proportional to the sizes of the ions ions involved and also inversely proportional to the sizes of the ions ions involved and directly proportional to the sizes of the ions. involved but independent of the sizes of the ions. involved and inversely proportional to the sizes of the ions 44. Consider the molecule shown below. What is the hybridization at each of the indicated carbons? 3 A) I sp II. sp II. sp II. sp II. sp II. sp III, sp B) I. sp C) I. sp D) Isp

Explanation / Answer

43. Option E, lattice energy is directly proportional to charge on the ion and inversely proportional to size of ion. Order follows :Bivalent-Bivalent >Bivalent - Monovalent >Monovalent -Monovalent

44.Option C,

Single bonded carbons are sp3 hybridization and double bonded carbons are sp2 and triple bonded carbons sp hybridization.
