D were 1641.69 cm-1 (Amide)‚ 1126.43 cm-1 (C-N bond)‚ and 1384.20 cm-1 (C-N bond). Using the functional groups and the melting and boiling point of each unknown a list of possible identities was generated. The identity of unknown liquid D was 2‚6 dimethyl pyridine‚ and the identity of unknown solid D was benzophenone.

Caffeine is a drug commonly used as a central nervous system stimulant. It is found in plants like coffee and tea. Caffeine can also be found in soft drinks‚ and it is regarded as the most widely consumed stimulant drug in the world based on Nehlig‚ Daval‚ & Debry (1992) research. The interaction of caffeine with adenosine receptors in the brains makes an individual more alert. A moderate intake of caffeine results in small healthy risks while high doses could be a catalyst to negative effects like

7. Modelling Polyethylene As mentioned previously‚ PE is one of the most important polymers in the world. ADMET has been used to systematically model commercially relevant polymers‚ specifically PE and copolymers of ethylene and another monomer. ADMET is capable of producing PE with specific sequences of monomer units‚ as well as random copolymers via copolymerization with 1‚9-decadiene. The ability to precisely synthesize these polymers has opened the door to exploring the molecular origins of

and functional groups will be grouped together in alphabetical order. (The prefixes di-‚ tri-‚ etc. are not taken into consideration for grouping alphabetically. For example‚ ethyl comes before dihydroxy or dimethyl‚ as the "e" in "ethyl" precedes the "h" in "dihydroxy" and the "m" in "dimethyl" alphabetically. The "di" is not considered in either case). When both side chains and secondary functional groups are present‚ they should be written mixed together in one group rather than in two separate
