Question

Quizplus · Accepted Answer

The nitrogen-hydrogen bonds in ammonia are polar because nitrogen is more electronegative than hydrogen, causing the electrons to be slightly closer to nitrogen than hydrogen. This creates a partial negative charge on the nitrogen and a partial positive charge on the hydrogens. Additionally, the ammonia molecule is asymmetrical, with the lone pair of electrons on nitrogen creating a region of partial negative charge, making the entire molecule polar.
