Question

which of the following molecules contains at least one atom that has less than a complete octet (excluding hydrogen)? you can consider structures that are both radicals or non-radicals. select all that apply however marks will be deducted for incorrect choices. question 2select one or more: hcl nh3 o2n-no2 h2o no bh3 sf6

Answer 1

NO, BH3 and O2N-NO2 are molecules that have at least one atom with an incomplete octet, categorizing them as odd-electron or electron-deficient molecules.

Step-by-step explanation:

The molecules that contain at least one atom with less than a complete octet, excluding hydrogen, from the provided list, are NO, BH3, and O2N-NO2 (as part of the nitrite ion, one nitrogen has an incomplete octet). These molecules are an example of electron-deficient molecules or odd-electron molecules.

NO and O2N-NO2 are odd-electron molecules because they have an unpaired electron, and BH3 is an electron-deficient molecule as boron has only six valence electrons in its stable form.
