Question 15 Give either the name or the formula for each of the covalent molecules. a. \( \mathrm{N}_{2} \mathrm{O} \) b. \( \mathrm{Boron}^{2} \) triiodide c. \( \mathrm{PCl}_{5} \) d. HBr e. \( \mathrm{Sulfur} \mathrm{hexafluoride}_{\text {f. } \mathrm{IBr}_{3}} \)

Diving into the world of covalent molecules can be a delightful ride! For \( \mathrm{N}_{2} \mathrm{O} \), it’s known as dinitrogen monoxide, commonly referred to as nitrous oxide or "laughing gas"—it brings a giggle to dentists’ offices! As for boron triiodide, its formula is \( \mathrm{BI}_{3} \). It’s a classic example of boron bonding, where one boron atom shares electrons with three iodine atoms, creating a rather interesting compound. Next up, \( \mathrm{PCl}_{5} \) is called phosphorus pentachloride, perfect for foiling plans in chemical synthesis! Then there’s HBr, which goes by the simple name hydrogen bromide—do not mix it up with H2O at your next cocktail party! Lastly, sulfur hexafluoride, \( \mathrm{SF}_{6} \), is known for its insulating properties and can even give your voice a funny twist if you inhale a bit—sounding like a chipmunk on helium! And let’s not forget \( \mathrm{IBr}_{3} \), or iodine tribromide, a chemical that likes to play with its halogen friends, creating a bold blend of iodine and bromine.
