Question

Explain the formation of H2 molecule on the basis of VBT.

Class 11

Answer 1

Your answer is ---

firstly we know about what is VBT (i.e, Valence bond theory )

▪️this theory tell us that covalent bond is formed by overlapping of atomic overlapping .

Now, come to the given question .

Formation of H2

In H2 their are 2 atoms of hydrogen

so , first orbital of H is overlap with orbital of second H atom .

Hope it helps you

Answer 2

Answer:

The elecronic confguration of hydrogen is 1$s^{1}$

.

Thus, it contains one unpaired electron in 1s orbital.

Two H atoms, each having one unpaired electron, combine and share their electron to form a covalent bond in which two electrons are paired.
