Question

Which of the following characteristics apply to nitrogen triiodide?1. non-polar molecule2. polar bonds3. trigonal-pyramidal molecular geometry4. sp2 hybridized

Answer 1

Nitrogen triiodide is a polar molecule with polar bonds and a trigonal-pyramidal molecular geometry.

Step-by-step explanation:

Nitrogen triiodide (NI3) is a polar molecule with polar bonds and a trigonal-pyramidal molecular geometry.

1. The molecule is polar because it has polar bonds. The nitrogen atom and each of the iodine atoms have different electronegativities, resulting in unequally shared electron pairs and polar bonds.
2. The molecular geometry of NI3 is trigonal-pyramidal, meaning the central nitrogen atom is bonded to three iodine atoms and has one lone pair. This arrangement creates a trigonal base with a lone pair at the apex.

Therefore, the characteristics that apply to nitrogen triiodide are polar bonds and a trigonal-pyramidal molecular geometry.

Answer 2

(2) polar bonds, (3) trigonal-pyramidal molecular geometry.

Step-by-step explanation:

NI3 has a tetrahedral electronic geometry with 3 bonds and a lone pair. This is a trigonal pyramid molecule geometry that has overall polarity due to the lone pair.

so (2) polar bonds, (3) trigonal-pyramidal molecular geometry.

these both answer will apply.
