CH.COCH Methyl ethanoate has 2 types of hydrogen atoms,so we see two peaks in the spectrum at about 2.1 and 3.7 ppm. The peak at 3.7 ppm is due to the-OCH3 group since the electronegative-0-deshields the methyl group. The integrations are 1:1 since there are 3H of each type. Integral 1 11 10 9 6 4 ppm
