Compound names

[Cassandra_1K]

Are we expected to know the names of compounds for exams? If so which ones?

[FDeCastro_1B]

My TA said that we'll be given the formulas from the compound names we see on the test. Apparently naming compounds and writing its formulas will be introduced to us later on in the quarter.

Hi all,

I agree with above, however, you should be aware of the basic naming rules including prefixes and suffixes. These are very important in your chemistry career, and is this is only a review of high school chemistry topics, don't be surprised if they show up on the test and something isn't provided.

My TA said that we do not need to know the names of the compounds yet, they will be given to us on the test

I don't think we have to know all the naming rules at the moment, but I think it would be useful to know some basics since they keep appearing in the homework:
If the compound is ionic, you add an "ide" to the end (e.g. NaCl is sodium chloride)
Useful Polyatomics: (NO3 nitrate, NO2 nitrite, ClO4 chlorate, SO4 sulfate, PO4 phosphate, CH3COO acetate)
Hope this helps.

I don't believe that we have to know all the compound's names but it definitely will be useful for not only this class but for future classes in the future.

[Brynne Burrows 3K]

We will be given the necessary compound names on tests, so no we do not have to memorize them.

Does anyone know what page in the book has the prefixes and suffixes and what they are?

[Jennifer Yang 3F]

All the compound naming related materials are on page 60-67!

Does anyone know how to determine what the formula for nitrous acid is? Are there rules that can help with this?

[JasonKwon_3k]

When determining the formula for nitrous acid, you look at the suffix of "nitrous", that being "-ous". This is a classification of an oxoacid that refers to the compound with fewer oxygen atoms (as opposed to "-ic" referring to a compound that has more oxygen atoms). Additionally, since it is an acid, there would be a proton attached to the molecule, coming at the front when referencing a formula. In the end, you end up with HNO2 being nitrous acid and HNO3 being nitric acid.

How would we know what the chemical formula is when given the compound names?
