Question
The vinyl region of the proton NMR spectrum of a mixture consisting of compounds F and G shows a triplet at 5.5 ppm (step height is 25 mm) and a doublet at 5.6 ppm (step height is 75 mm). What is the composition of the mixture (as % compound F)? Please carry maximum number of significant figures through to final answer then round to a whole number. Enter just the numerical value expressed as a whole number. Don't be alarmed when Canvas adds trailing zeros to the number you type in. This action will not affect the grading of your answer.
Explanation / Answer
compound G would show a triplet at 5.5 ppm
compound F would show a doublet at 5.6 ppm
So, the composition of the mixture in terms of F
= 75 x 100/100
= 75%
