Question

lets check your understanding. drag and drop the correct structural formula to the matching molecular formulas and names below. ammonia nh₃ water h₂o did you fully understand the concept covered in this

Explanation:

Step1: Recall ammonia structure

Ammonia ($NH_3$) has a nitrogen - atom bonded to three hydrogen atoms with a lone - pair on nitrogen. The correct structural formula is the one with a nitrogen atom in the center and three hydrogen atoms bonded to it.

Step2: Recall water structure

Water ($H_2O$) has an oxygen atom bonded to two hydrogen atoms and two lone - pairs on oxygen. The correct structural formula is the one with an oxygen atom in the center and two hydrogen atoms bonded to it.

Answer:

Ammonia $NH_3$: The structural formula with a nitrogen atom in the center and three hydrogen atoms bonded to it.
Water $H_2O$: The structural formula with an oxygen atom in the center and two hydrogen atoms bonded to it.
