State balanced reactions for the bromine as well as permanganate tests for 1-methylcyclohexene. Explain which one of the following compounds would give tests positive- cyclopentane, 2-chloropentane, cyclopentene.
Determine the freezing point of an aqueous solution that is 1,7 m in ethylene glycol. The freezing point depression constant for water is 1.86°C/m The freezing point of pure water is 0.0°C.
The best means of personal protection from radiation for emergency responders is the implementation of three basic principles: time, distance and shielding.
For methanol, CH3OH, the molar enthalpy of fusion is 3.16 kJ/mol at the melting point T=175.2 K. Calculate the freezing point depression constant,k, of methanol
The ketone used was cyclopentanone and the aldehyde used was benzaldehyde. First cyclopentanone was dissolved in 95% ethanol. Then benzaldehyde was added along with NaOH to the mixure. The solution was then mixed creating the aldol condensation pr..
