Question

Why NaCl and BeО have same internuclear distance but BeO has higher melting point than NaCl?

Answer 1

BeO has higher melting point than NaCl because of stronger force of attraction between atoms.

Explanation:

Because BeO atom share two electrons and form double bond, and NaCl form only a single bond, hence it requires little energy to break down then BeO.

Answer 2

Answer:

The correct answer of this question is stronger force of the attraction between atoms.

Explanation:

Given - NaCl and BeО have same internuclear distance but BeO has higher melting point than NaCl .

BeO has the higher melting point than NaCl because of stronger force of the attraction between atoms. Because BeO atom share two electrons and form the double bond and NaCl form only a single bond hence it is require little energy to break down than BeO.
