Question

What is the empirical formula for ${\text{B}}_3{\text{N}}_3{\text{H}}_6$?

• A. $\text{BNH}$
• B. ${\text{B}}_2{\text{N}}_2{\text{H}}_3$
• C. ${\text{BNH}}_2$
• D. ${\text{B}}_2\text{NH}$

Answer 1

The correct option is C ${\text{BNH}}_2$

The empirical formula of a compound is the simplest formula, which gives the simplest whole-number ratio of atoms of different elements present in one molecule of the compound.
In the case of ${\text{B}}_3{\text{N}}_3{\text{H}}_6$, the simplest ratio to indicate the number of atoms of $\text{B}$, $\text{N}$, and $\text{H}$ would be obtained by dividing $3,3,$ and $6$ by $3$. So, the empirical formula is ${\text{BNH}}_2$.
