Thus a solution α-naphthol 1a‚ 4-methylbenzaldehyde 2a and tert-butyl isocyanide 3a in EtOH was magnetically stirred at 45 C for 12 hours under an oxygen atmosphere with an equimolar ratio of the three reactants. TLC monitoring of the reaction mixture exhibited formation of a new product‚ which was purified (Table 1‚ entry 1). Identification of its structure by NMR spectroscopy revealed that it was 2-(4-methylbenzoyl)-1-naphthyl N-(tert-butyl)carbamate (4a). Next‚ in order to improve the yield of 4a

by : Directorate of Education‚ Delhi SOME IMPORTANT REASONING BASED QUESTIONS OF ORGANIC CHEMISTRY 1. Chlorobenzene is less reactive than chloromethane. Ans. In chlorobenzene‚ each carbon atom of benzenering is sp2 hyridised and is electron withdrawing. Chlorine atom donates a lone pair of electron and acquire positive charge. The negative charge is delocalised on ortho and para position by resonance. C-Cl bond acquires partial double bond character and is 169 pm as compared to 17.0 pm in chloromethane

moves slowly through the packed column. In this experiment‚ an adsorption chromatography column was constructed using silica gel as the adsorbent. A 50:50 mixture of ferrocene and acetylferrocene was then separated using the eluents hexane and tert-butyl methyl ether (TBME). The less polar ferrocene was attracted to the less polar hexane‚ so as the hexane passed through the stationary phase‚ the ferrocene moved with it and the acetylferrocene was left behind. When TBME was passed through the stationary

Kinetics of an SN1 reaction: the effect of solvent on rate Object The purpose of this experiment is to determine the rate of hydrolysis in acetone/water (50/50 v/v and 60/40 v/v). Background and Theory An SN1 reaction of tert-butyl chloride takes place in two steps. First‚ the Alkyl Halide will leave the molecule. In this step the bond is breaking‚ which takes a longer amount of time‚ so it will determine the rate of the reaction. As a result‚ it forms a tertiary carbocation‚ since this
