The boiling points of some group 7A hydrides are tabulated below.
11111nata11111 [884]

hey there!:

In the case of ammonia, the hydrogen bond is formed using the lone pair present in nitrogen and the hydrogen having δ+ charge (due to bonding with electronegative N) of another ammonia molecule. Thus the inter molecular attraction increases which in turn increases the boiling point .

Option B is the correct answer.

Hope this helps!

When atomic orbitals of two nuclei overlap, the mutual attraction between a negatively charged electron pair and the two positiv
Lera25 [3.4K]

Answer: Option (A) is the correct answer.

Explanation:

It is known that when sharing of electrons take place between two combining atoms then the bond formed is known as a covalent bond. In general, a covalent bond is formed between two non-metal atoms.

For example, the compound HCl has a covalent bond between the hydrogen and chlorine atom. As hydrogen atom has 1 valence electron and chlorine atom has 7 valence electrons.

So, in order to attain stability both these atoms will share their valence electrons and hence, a covalent bond is formed.

On the other hand, when an electron is transferred from one atom to another then it tends to form an ionic bond.

For example, the compound NaCl has an ionic bond.

Thus, we can conclude that when atomic orbitals of two nuclei overlap, the mutual attraction between a negatively charged electron pair and the two positively charged nuclei forms a covalent bond.
