SOLUTIONS TO TEXT PROBLEMS 3.1 (b) The sawhorse formula contains four carbon atoms in an unbranched chain. The compound is butane, CH:CH,CH, CH3 CH3 HH H-H CH ()Rewrite the structure to show its constitution. The compound is
The triacylglycerol shown in text Figure 26.2a, with an oleyl group at C-2 of the glycerol unit and two ste earyl groups at C-I and C-3, yields stearic and oleic acids in a 2 I molar ratio on hydrolysis. A constitutionally isomeric structure in which the oleyl group is attached to C-1 of glycerol would yield the same hydrolysis products
Different metal containing compounds emit colored light when fireworks burn. This colored light is a combination of series of colors called spectral pattern.(谱带) Each element emits its own characteristic spectral pattern, which can be used to identify the element. This allowed the scientists in 1900s to develop models of the atom's internal structure
