Class XI

Bond angle helps us in
  1. determining molecular size
  2. determining molecular shape
  3. determining the reactivity of the element
  4. determining the stability of the element
The bond formed, as a result of the electrostatic attraction between the positive and negative ions was termed as
  1. single covalency
  2. electrovalent bond
  3. coordinate bond
  4. covalent bond
The formation of the Cl2 molecule can be understood in terms of the sharing of a pair of electrons between the two chlorine atoms, each chlorine atom contributing one electron to the shared pair. Choose the most appropriate name of the bond that is formed
  1. ionic bond
  2. double bond
  3. multiple bond
  4. a single covalent bond
bond lengths are lower in elements having
  1. crystal structure
  2. double bond
  3. single bond
  4. triple bond
Inertness of noble gas was observed to be due to their electronic configurations: Choose the most appropriate
  1. Outermost orbitals of the noble gases are fully filled.
  2. Noble gases form ions to complete their outermost orbitals
  3. Total number of electrons in the outermost shell is duplets
  4. Atomic mass is low so they are stable
