Calculate the net charge of the molecule

• A. -1
• B. 0
• C. +1
• D. +2

Answer: (C)

Verified step by step guidance

1. Identify the atoms in the molecule and their typical valence states. Carbon (C) typically has a valence of 4, nitrogen (N) has a valence of 3, hydrogen (H) has a valence of 1, and bromine (Br) has a valence of 1.
2. Examine the structure to determine the formal charge on each atom. Formal charge is calculated using the formula: Formal Charge = (Valence electrons) - (Non-bonding electrons) - (Bonding electrons/2).
3. Calculate the formal charge for each atom in the molecule. For example, nitrogen typically has 5 valence electrons, and in this structure, it is bonded to three atoms and has no lone pairs, which may result in a positive formal charge.
4. Sum the formal charges of all atoms in the molecule to determine the net charge. Consider the contribution of each atom's formal charge to the overall charge of the molecule.
5. Interpret the calculated net charge in the context of the problem statement, which suggests the correct answer is +1. Ensure that the calculated net charge aligns with this expected result.
