What can cause a false positive on Tollen's Test? My compound is a ketone, deemed to be 5-methyl-2-hexanone, however a positive result was produced when conducting the Tollen's Test. I know it must have been a false positive since my compound was not an aldehyde, but what could be some reasons that could have caused this?

The question is based on the identification of an unknown compound to be an alcohol, aldehyde or keytone. Give three reasons why acetone may interfere with your result. I think that the presence of acetone will give false positives for Iodoform reaction, DNP test while the unknows might not be (methyl ketones or aldehydes or ketones) for that matter, what could a third reason be?

Hi I just need a little help breaking down some information. I have an unknown, which i distilled on a microscale. The boiling point I got was 102 C. I performed a DNPH test which came back negative so its not an aldehyde or ketone, also a chromic acid was positive for a primary or secondary alcohol, and potassium permanganate negative for alkene or alkyne. My IR came back with 3 sp3 C-H peaks an O-H and C-O. The possible...

CONTEXT So we did an Sn1 reaction in chem lab to convert t-butyl alcohol to t-butyl chloride by the following reaction C4H10O + HCl --> C4H9Cl + H2O We did this by mixing the HCl and the t-butyl alcohol in a separatory funnel, then we collected the organic layer that formed and vacuum distilled the product. QUESTIONS What is something that could cause a low yield in this experiment? we got a 26% yield, I was thinking maybe heating up...

I think I can pinpoint my confusion a bit better. Here comes my updated question (I'm not sure what the standard way of doing things is - please let me know if I should delete the old version). The major change is that I removed focus from the third question which probably is a purely mathematical question (in the notation below, it asks what properties of (M,T) together with (M,T) being consistent, forces (M,T) to be unique.). Say that a...
