Answer:
The correct answer is option 3)
Explanation:
negative charge should be given to Nitrogen not to Carbon
By the way are you a student of Brilliant's (it looks exactly like my workbook)?
Answer:
The correct answer is option 3.
Explanation:
The atomic number of carbon is 6. It has 4 valence electrons. It shares its 4 valence electrons with 4 electrons of 4 other atoms to form 4 bonds. When C atom forms 4 bonds, it has no charge and is neutral in nature. When a carbon atom forms only 3 bonds and it has no unshared electron(s), then such carbon atom has unit positive charge. When a carbon atom forms only 3 bonds and it has one unshared electron pair, then such carbon atom has unit negative charge.
In the resonance structure given in the option (C), the carbon atom is surrounded by 8 valence electrons. Yet carbon atoms are shown to have positive charge. This is not possible. Instead of carbon atom, the positive charge should have been on nitrogen atom
This is because, nitrogen atom forms 3 covalent bonds and one coordinate bond. Nitrogen atoms donate its lone pair of electrons to carbon atoms to form a coordinate bond. In turn, the pi electrons of carbon-oxygen double bonds are given to oxygen atoms. So oxygen atom gains unit negative charge.
.Resonance structures are the Lewis structures that describe the delocalisation of electrons in a molecule.
