Atoms combine to form molecules to get stability. During the formation of molecules octet may be attained. But `BF_3` is an exception to octet rule.
Explain the stability of `B_2H_6` with the help of a diagram.

Atoms combine to form molecules to get stability. During the formation of molecules octet may be attained. But BF_3 is an exception to octet rule. As BF_3 , B_2H_6 is also an electron deficient compound. Comment.

In the following question, an Assertion (A) is followed by a corresponding Reason (R). Use the following keys to choose the appropriate answer. Assertion : In the formation of water molecule, both hydrogen and oxygen atoms attain octet of electrons. Reason : Oxygen atom forms two ionic or electrovalent bonds with two hydrogen atoms.

The attractive force which holds atoms together in a molecule is called a chemical bond.Explain the formation of a H_2 molecule on the basis of the valence bond theory (VBT)
