On topscore test one question 48 says: which one is not a "chlorate"?

A. ClO2 -
B. ClO3 -
C. ClO4 -
D. ClO4 2-
E. All are "chlorates"

The answer is d because ClO4 2- does not exist. But my gen chem textbook names A. ClO2 - as chlorite so is it still a chlorate because it is in the oxoanion family with chlorates? Please explain b/c I am confusing myself over things that should not be hard.

I missed the same question on the same test. I used the same reasoning as you.... 🙁 What'd you make on that G Chem practice test?

A 16. Ugghhhh I hate Gen Chem so much. After I review any practice test/ subject test to see what I missed I think I understand the problems...... and then I never see that type of problem again. It's like each test asks questions about some new concept that I don't know. 😡

Sorry to rant... but studying this stuff sux

I hear ya. I got a 17, and I'm sort of worried. I was hoping for at least a 20 on the real thing. Maybe this topscore is too hard for GChem. Lol, trying to stay positive.. 🙂 Good luck w/ your studying...

ACID NAMING CONVENTIONS ARE AS SUCH WHEN OXYGEN AND HYDROGEN ARE INVOLVED:
HCLO3 IS CHLORIC ACID IT HAS AS MANY O'S AS IT SHOULD (4 BONDS).
HCLO4 IS PERCHLORIC ACID, IT HAS ONE MORE O THAN IT SHOULD.
HCL02 IS CHLOROUS ACID, ONE LESS THAN IT SHOULD
HCL0 IS HYPOCHLOROUS ACID, HAS TWO LESS THAN IT SHOULD.

ANIONS FORMED WHEN H+ DEPARTS ARE THE RESPECTIVE CHLORATES:
Clo2 is chlorite
clo3 is chlorate
clo4 is perchlorate
clo is hypochlorate

same convention for HNO3 and H2SO4

ClO- is hypochlorite, just to be precise.
