Esterification (shown below) is a reaction converting a carboxylic acid to its ester. It involves only the carbonyl carbon. Esterification of $(-)$ lactic acid with methanol yields $(+)$ methyl lactate. Assuming that there are no side reactions,what is true about this reaction?

Product $(X)$ is

An organic compound having molecular formula $C_2H_6O$ undergoes oxidation with $K_2Cr_2O_7 / H_2SO_4$ to produce $X$ which contains $40\,\%$ carbon,$6.7\,\%$ hydrogen and $53.3\,\%$ oxygen. The molecular formula of the compound $X$ is

Which of the following is the correct order of acidic strength?
