The Claisen condensation converts two molecules of an ester into a B-keto ester. The reaction starts with the ester in an alkoxide/alcohol solution and is worked up with acid to form the neutral B-keto ester product. in 1. "OCH,CH3 / CH;CH2OH 2 2. H30* Show the curved-arrow mechanism for the Claisen condensation of ethyl ethanoate treated with ethoxide ion. Include all formal charges and nonbonding electrons. In each step, draw only the species that react in that step. If an enolate resonance form is possible, draw only the carbanionic form. If a CH, group is being deprotonated, draw all H's on the reacting site. Tip: always omit ethanol byproducts. tep 4c: Draw the resulting structure or structures indicated by the curved-arrow mechanism shown. Include formal charges, ut not lone pairs. :0: :0: H H 1
Analyzing Infrared Spectra
The electromagnetic radiation or frequency is classified into radio-waves, micro-waves, infrared, visible, ultraviolet, X-rays and gamma rays. The infrared spectra emission refers to the portion between the visible and the microwave areas of electromagnetic spectrum. This spectral area is usually divided into three parts, near infrared (14,290 – 4000 cm-1), mid infrared (4000 – 400 cm-1), and far infrared (700 – 200 cm-1), respectively. The number set is the number of the wave (cm-1).

It is the analysis of the structure of cyclohexaone using IR data interpretation.
IR Spectrum Of Anisole
Interpretation of anisole using IR spectrum obtained from IR analysis.
IR Spectroscopy
Infrared (IR) or vibrational spectroscopy is a method used for analyzing the particle's vibratory transformations. This is one of the very popular spectroscopic approaches employed by inorganic as well as organic laboratories because it is helpful in evaluating and distinguishing the frameworks of the molecules. The infra-red spectroscopy process or procedure is carried out using a tool called an infrared spectrometer to obtain an infrared spectral (or spectrophotometer).
Step 4c: Draw the resulting structure or structures indicated by the curved‑arrow mechanism shown. Include formal charges, but not lone pairs.
