Spectrum 1 shows,
Two peaks above 100 ppm for olefinic carbons
one peak below 80 ppm for carbon next to oxygen
Possible structure,
CH2=CH-O-CH3
--
Second spectrum shows,
all peaks below 50 ppm
So all carbons are aliphatic in nature
Total four peaks for four non-equivalent carbons
Possible structure,
(CH3)2CH-CH2-CH2-Br
