Find the cooling achieved and the work by the compressor. Is the compressor isentropic? IF the cooling is 300 KJ/kg and the work by the compressor is 300 kJ/kg what is the coefficient of performance for the system?
Why is benzyne such a reactive molecule/why is it so unstable? (Is there any reason other than the fact that triple bonds are not stable within a 6-membered ring?)
When CO2 is bubbled through an ether solution of benzyl magnesium bromide, and the resulting mixture is acidified, phenyl acetic acid is produced. Any unreacted benzyl magnesium is converted to toluene.
