  • Solution

    When gas is compressed its entropy decreases so, ?S is negative.

The molecule having smallest bond angle is :

  • Solution

    All the members form volatile halides of the type AX3. All halides are pyramidal in shape. The bond angle decreases on moving down the group due to decrease in bond pair-bond pair repulsion.

Four diatomic species are listed below in different sequences.Which of these presents the correct order of their increasing bond order?

  • Solution

In which of the following pairs, the two species are iso-structure?

  • Solution

    Both BrO3 and XeO3 have sp3 hybridization but due to presence of one lp of electrons they have trigonal pyramidal geometry.

Dipole moment of CO2 is zero which implies that

  • Solution

    O?- = C?+ = O?- linear molecule hence ? = 0.

In which of the following pairs hydrogen-bonding is not possible ?

  • Solution

    In H - bonding atoms involved are F, O and N.

The correct statement with regard to \(H_{2}^{+}\) and \(H_{2}^{-}\) is

  • Solution

  • Solution

If Nx is the number of bonding orbitals of an atom and Ny is the number of anti bonding orbitals, then the molecule/atom will be stable if

In \(O_{2}^{-}\), O2 and \(O_{2}^{-2}\) molecular species, the total number of anti bonding electrons respectively are
