Chemical Formula Name

[Maria Trujillo 1L]

So the other day I was doing a HW problem, specifically 3.39, part C. I noticed that the name of the compound was sodium hypochloride. My first instinct was to write out Na for sodium and then H and Cl for hypochloride. However after checking my answer I discovered that hypochloride is composed of O and Cl. How are you supposed to know what elements are being used in the name of a compound? Is there a rule or ia chart? Thank you!

I think for the test he would give us the chemical formula since we have not gone over how to write the chemical formula from just the name.

The moderators on this website have already confirmed that we will be given the actual formulas on the test. So we don't need to know how to figure out the formulas by looking at the names :)

My TA also told us that we are not expected to know how to write out names of compounds.
