Does Rubbing Alcohol + Bleach really produce Chloroform?

A lot of sources on the internet claim that mixing rubbing alcohol with chlorinated bleach produces chloroform.


Rubbing alcohol is Isopropanol, and bleach is Sodium Hypochlorite. Neither of these are the reagents for the [Haloform reaction](https://en.wikipedia.org/wiki/Haloform_reaction). So I ask, is chloroform really produced, and if so, how?




Yes, rubbing alcohol and bleach could produce chloroform when mixed, if the alcohol is isopropyl-type rubbing alcohol and the bleach is hypochlorite-type bleach. Isopropyl alcohol is indeed a substrate for the haloform reaction, according to Fuson and Bull, *Chem. Rev.*, **15**, 275 (1934) and references therein.


I can't recall the reference off the top of my head, but I believe in "dilute" solutions approaching "bleach and alcohol" the chlorination tends to continue and produces carbon tetrachloride as the main product.
