technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol‚ then characterized using melting point analysis. Introduction: In this experiment we learnt on carbonyl compounds‚ enols and enolates. We also learnt two different techniques

oxidizer that you may not have discussed in lecture called Oxone ®. Oxone is a persulfate mix that reacts with acetone to produce dimethyldioxirane. Procedure: Oxone reaction Dissolve 0.40 g oxone ® in 2.0 mL of water by shaking vigorously in a sealed vial. (Caution! Be sure the vial is sealed because oxone is a strong oxidizer.) Dissolve 50 L of cyclohexene in 2.0 mL of acetone in a small Erlenmeyer flask. Cool the cyclohexene solution in an icebath‚ then add the oxone solution dropwise

Besides‚ I observed that biphenyl‚ butyl acetate‚ glycerol and motor oil are nonpolar substance. These compounds were soluble in hexane. Meanwhile‚ magnesium

experimented on the reactions of the chemicals that undergoes SN1 or SN2 reaction. Nine different compounds were given to be examined with two reagents - NaI in acetone and AgNO3 in ethanol. The SN1 reaction happens in AgNO3 in ethanol reagents‚ and SN2 reaction is in NaI in acetone. Procedure: Following the lab manual. Results: compound NaI /acetone (SN2) AgNO3/ethanol (SN1) Bromobenzene NR NR Bromocyclopentane X 2 sec Bromocyclohexane NR 4 sec 2-bromobutane 5 min 2 sec 2-chlorobutane
