The potential sources of error in the analysis of the flames should be explained. Concept Introduction: Emission spectra is given by an atom of an element when it absorbs sufficient amount of energy, by means of heat, electric current etc. so that valence electrons in its shell gets excited and jumps to a higher level from its initial lower level. When it comes back to lower level, the electron loses the energy in the form of radiation. The energy so liberated has a particular wavelength corresponding to which the color of the wave is determined. There are two types of emission spectra- continuous and discrete emission spectra. Prism and diffraction grating are used to see the mixture of colors in light. A diffraction grating is a device that deflects light through an angle that depends on the wavelength of the light. Light falls on the grating surface with different colors at a certain angle. This creates diffraction pattern with all the different colors other than yellow, orange and blue comprising the light, scattered at different angles.

13.84. Chlorine atoms react with methane, forming HCI and CH3. The rate constant for the reaction is 6.0 × 107 M¹ s¹ at 298 K. When the experiment was run at three other temperatures, the following data were collected: T (K) k (M-1 s-1) 303 6.5 × 107 308 7.0 × 107 313 7.5 x 107 a. Calculate the values of the activation energy and the frequency factor for the reaction. b. What is the value of the rate constant in the lower stratosphere, where T = 218 K?

My Organic Chemistry textbook says about the formation of cyclic hemiacetals, "Such intramolecular reactions to form five- and six-membered rings are faster than the corresponding intermolecular reactions. The two reacting functional groups, in this case OH and C=O, are held in close proximity, increasing the probability of reaction."According to the book, the formation of cyclic hemiacetals occurs in acidic conditions. So my question is whether the carbonyl group in this reaction reacts first with the end alcohol on the same molecule or with the ethylene glycol. And, given the explanation in the book, if it reacts first with ethylene glycol before its own end alcohol, why would it? I don't need to know the final answer. I need to know WHY it would not undergo an intermolecular reaction prior to reacting with the ethylene glycol if that is the case. Please do not use an AI answer.
