  • Answer: 2 📌📌📌 question Which molecule has a Lewis structure that does not obey the octet rule? N2O CS2 PH3 CCL4 NO4 - the answers to estudyassistant.com Mar 29, 2019 · Use the octet rule to determine the number and type of bonds present. Each atom’svalence shell should contain 8 electrons for the molecule to be stable. Some atoms may be double or triple bonded to achieve this. In a water molecule, add a single bond from the oxygen to both hydrogens. The hydrogens are not bonded to each other.
