An unknown compound described by the spectra below is a liquid (b.p. 161 C) with a measured elemental composition of 38.0% C, 7.4% H, and 37.6% Cl. Determine the structure of the unknown compound.
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).

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).
The mass spectrum, IR-spectra and the 1H-NMR spectra of a unknown organic compound is given. The unknown organic compound is said to have a composition of 38.0 % C, 7.4 % H and 37.6 % Cl.
The mass spectra of the given compounds have the molecular ion peak around 95 while the base ion peak at 58.
The IR spectra of the unknown compound have a sharp peak of medium intensity between , a broad peak of large intensity between , a broad peak of medium intensity between and a sharp peak around .
The 1-H NMR spectra of the unknown compound have a total of three different peak. The 1-H NMR consists of a triplet around , a quartet around and a singlet around . The peak present at 0 ppm is due to the presence of Tetramethyl Silane which is used as a reference.
