1.5.1 Comparison of Three Isomers of Butanol Introduction: An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. The location of this hydroxyl functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). If the OH is bonded to only one other carbon‚ it is a primary alcohol (eg. 1-butanol); if bonded to two other carbons‚ it is a secondary alcohol (eg. 2-butanol);

perfection. The Geometric period of Greek art takes its name from the geometric patterns on vases from this era. However geometric shapes did not appear for the first time in this period. Circles‚ lines‚ spirals‚ triangles‚ and squares used in prior cultures like in Mesopotamia‚ West Asia and Asia Minor‚ Central Europe‚ and in many vessels of the Minoan and Mycenaean civilization. The Arrangement on the surface of their vessels was one thing that distinguishes the Greek geometric art. In the past

In antiquity‚ geometric constructions of figures and lengths were restricted to the use of only a straightedge and compass (or in Plato’s case‚ a compass only; a technique now called a Mascheroni construction). Although the term "ruler" is sometimes used instead of "straightedge‚" the Greek prescription prohibited markings that could be used to make measurements. Furthermore‚ the "compass" could not even be used to mark off distances by setting it and then "walking" it along‚ so the compass had to

Abstract In this experiment‚ the nature of linkage isomers will be observed on the example of nitritopentaamminecobalt(III) Chloride and nitropentaamminecobalt(III) Chloride. Their relative stability will be compared on standard conditions and the infrared spectroscopy of both the isomers will be obtained to analyze the characteristic absorption bands for the nitro and nitrito group. Yield for nitritopentamminecobalt(III) Chloride was obtained to be = 1.9221 g(73.24 %) and yield for nitropentamminecobalt(III)

& Sums Introduction A geometric sequence is a sequence such that any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r. The common ratio (r) is obtained by dividing any term by the preceding term‚ i.e.‚ where | r | common ratio | | a1 | first term | | a2 | second term | | a3 | third term | | an-1 | the term before the n th term | | an | the n th term | The geometric sequence is sometimes called

Susan Dellinger: Psycho-Geometrics I love great public speakers. I’ve seen some great ones in my life. They captivate the audience‚ entertain‚ educate‚ even make you laugh. The most important part is that they make it look effortless and natural. Susan Dellinger‚ the speaker for the video‚ "Psycho-Geometrics" is one of them. Her presentation was incredibly entertaining‚ interesting‚ and funny. But the focal point was definitely Ms. Dellinger herself. The level of excitement in her voice was great

Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚ for example
