type in the formal charge of the central br in the molecule below, as the molecule is currently drawn…

Explanation:

Step1: Recall formal - charge formula

The formula for formal charge is $FC = V - N - \frac{B}{2}$, where $V$ is the number of valence electrons of the atom in isolation, $N$ is the number of non - bonding electrons, and $B$ is the number of bonding electrons.

Step2: Identify values for central Br

Bromine (Br) has 7 valence electrons ($V = 7$). In the given molecule, the central Br has 4 non - bonding electrons ($N = 4$) and 4 bonding electrons ($B = 4$).

Step3: Calculate formal charge

$FC=7 - 4-\frac{4}{2}=7 - 4 - 2=1$
