Ben and Jim are best friends and like playing pranks among themselves. Once Ben sent a fake phishing link to Jim to know his girlfriend's name but Jim was clever and instead of entering his girlfriend's name, he entered a code that was sent to Ben's email account. The code was


After 5 minutes he received an email from Jim, reading:

"Give her an IUSPAC name and find her name if you can"


Jim is really nuts about chemistry.

Can you guess his girlfriend's name?

  • $\begingroup$ I'm guessing IUSPAC is an anagram: anagram-solver.net/IUSPAC ... $\endgroup$

    $\begingroup$ @mestackoverflow iUPAC is a naming convention for organic chemical compounds (Jim is really nuts about chemistry), not sure if the extra S is intentional or typo $\endgroup$

    $\begingroup$ pubchem 9801 is prenylamine - not sure if that helps. $\endgroup$

After searching for some chemistry details

Found nothing about IUSPAC (May be some hint)

IUPAC : the IUPAC nomenclature of organic chemistry is a systematic method of naming organic chemical compounds as recommended by the International Union of Pure and Applied Chemistry (IUPAC)

Number 9801 is a pubchemID(dont know what that is) of:

whose IUPAC name is

Also looked for some synonyms of that:
So found 4 synonyms

(Out of which no one seems like a girls name)

Dont know what to do after this. May be this may help in further answers.


A wild guess. As others have noted

PubChem CID 9801 is prenylamine.
The chemical formula for prenylamine is: $C_{24} H_{27} N$.
If we rotate C by 24 places, we get A. Rotate H by 27 places gives I.
Putting this together gives AIN, which is an Arabic girls' name.
This, of course, ignores the IUSPAC part of the puzzle.
The wording suggests that maybe the answer is to give the IUSPAC name
of the compound as well as the girlfriend's name. If so, then as others have noted, the IUPAC (assuming this is what is meant) name of prenylamine is 3,3-diphenyl-N-(1-phenylpropan-2-yl)propan-1-amine.

  • $\begingroup$ shouldn't we rotate N by 1 place? $\endgroup$

  • $\begingroup$ @JonMarkPerry I considered that. It isn't usually written with a subscript, so I didn't rotate. I actually hope this isn't the real answer because it isn't very satisfying. $\endgroup$ Jun 27, 2016 at 13:11
