Chapter 3, Problem 5
Write the formula for each molecular compound. a. boron tribromide b. dichlorine monoxide c. xenon tetrafluoride d. carbon tetrabromide
Verified step by step guidance1
Identify the prefixes in the names of the compounds to determine the number of each type of atom in the molecule.
For boron tribromide, 'tri-' indicates three bromine atoms, so the formula is BBr_3.
For dichlorine monoxide, 'di-' indicates two chlorine atoms and 'mono-' indicates one oxygen atom, so the formula is Cl_2O.
For xenon tetrafluoride, 'tetra-' indicates four fluorine atoms, so the formula is XeF_4.
For carbon tetrabromide, 'tetra-' indicates four bromine atoms, so the formula is CBr_4.
