The product of the magnitude of the charge and the distance between the centres of positive and negative charge is called

Polarity in a molecule and hence the dipole moment depends primarily on electronegativity of the constituent atoms and shape of a molecule. Which of the following has the highest dipole moment?

The octet rule is not valid for which of the following molecules?

In the formation of hydrogen molecule, overlapping of atomic orbitals occur  which results in the pairing of electrons. These are:

Which of the following is a correct set of molecule, hybridisation and shape?

the valence shell electron pair repulsion (vsepr) theory helps in the

Which of the following elements will combine to form an ionic compound?

Which of the following compounds has/have all the atoms with a stable 8-electron inert gas configuration in their outermost shells?

H.O.H bond angle in water is

Which of the following have similar geometry?

The amount of energy required to break one mole of bonds of a particular type between two atoms in a gaseous state is called

If the molecules of HCl were totally polar, the expected value of dipole moment would be 6.12 D (debye), but the experimental value of dipole moment would be 1.03 D. Calculate the percentage ionic character.

Among LiCl, BeCl₂, BCl₃ and CCl₄, the covalent bond character follows the order

Identify the isostructural pair.

The electronegativity difference between N and F is greater than that between N and H; yet the dipole moment of NH₃ (1.5 D) is larger than that of NF₃ (0.2 D). This is because

Which one of the following has a regular tetrahedral structure?

Bond angle helps us in

N₂, CO and NO⁺ are isoelectronic molecules. Their respective bond order is :

in case of a heteronuclear molecule like HF, the shared electron pair between the two atoms gets displaced more towards fluorine since the electronegativity of fluorine is far greater than that of hydrogen. This results in the molecule a
