Question

Hi organic chemistry folks! Is there someone who can please edit any sentence structure problems (wording) and grammar issues for my short paragraph lab on simple distillation of an unknown liquid?

The purpose of this laboratory experiment was to perform a simple distillation in order to characterize via boiling point and IR spectrum of an unknown #3 volatile organic liquid. The first drop of the distillate had a distillation temperature of 58.0 °C and a constant rate of distillation of one drop per second throughout collecting 7 mL of the distillate. The observed boiling point reached a constant temperature of 65.0 °C throughout 2-7 mL of the collected distillate, which matches the literature BP range of tetrahydrofuran (bp 65-67 °C). The IR spectrum revealed Csp³-H stretches at a range of 2861-2933 cm^-1 along with a narrow C-O stretch at 1066 cm^-1. From these data, it was concluded that the purified unknown #3 contained tetrahydrofuran.

The purpose of this laboratory experiment was to perform a simple distillation of a volatile organic liquid in order to characterize the unknown compound #3 by its boiling point and IR spectrum. The first drop of the distillate collected had a distillation temperature of 58.0 °C. The liquid was collected (7 ml) at a constant rate of one drop per second at a constant boiling point of 65 oC maintained between 2-7 ml of distillate. The observed boiling point matches the literature BP range of tetrahydrofuran (bp 65-67 °C). The IR spectrum of the collected liquid showed peaks between 2861-1933 cm-1 due to Csp³-H stretching. Another peak at 1066 cm-1 was assigned due to C-O stretching. From these data, it was concluded that the purified unknown #3 is tetrahydrofuran.
