Question

Draw a line-bond structure for CBrN. Explicitly draw all H atoms. You do not have to include lone pairs in your answer. In cases where there is more than one answer, just draw one.

Answer 1

Br - C ≡ N

Step-by-step explanation:

To draw the Lewis line-bond structure we need to bear in mind the octet rule, which states that in order to gain stability each atom tends to share electrons until it has 8 electrons in its valence shell.

• C has 4 e⁻ in its valence shell so it will form 4 covalent bonds.

• Br has 7 e⁻ in its valence shell so it will form 1 covalent bond.

• N has 5 e⁻ in its valence shell so it will form 3 covalent bonds.

The most stable structure that respects these premises is:

Br - C ≡ N

It does not have any H atom.
