Well, the only way you would get clouds is evaporation, a liquid to a gas. (Change of matter) the clouds would not turn into rain without percipitation, gas to water. (Change of matter.)
Yes u are right :) FILTRATION IS THE CORRECT ANSWERR
Four option are provided as,
CH3CH2OCH2CH3
CH3CH2Cl
CH3CH2CH3
CH3OCH2CH2OCH3
CH3CH2Cl having 2 peaks of H NMR as 1st peak for quartet of 2 H and 2nd peak of triplet of 3 H and thus the ratio of both the peak is 2 :3 as the ratio indicates the number of hydrogen corresponds to each peak.
