Denatured alcohol is:

In esterification,the reactivity of alcohols is:

$A$ compound $A$ on oxidation gives acetaldehyde,and further oxidation gives an acid. After the first oxidation,the product reacts with ammoniacal $AgNO_3$ to produce a silver mirror. Compound $A$ is likely to be:

Ethyl hydrogen sulphate is obtained by the reaction of $H_2SO_4$ on

An alcohol $X$ $(C_5H_{12}O)$ when reacted with conc. $HCl$ and anhydrous $ZnCl_2$ produces turbidity instantly. The alcohol $X$ can be prepared from which of the following reactions?

$CH_3CH_2CH(OH)CH(CH_3)_2 + CH_3COCl \xrightarrow{\text{base}} CH_3CH_2CH(OCOCH_3)CH(CH_3)_2 + HCl$
In the above reaction,if the reactant alcohol is a pure $R$-isomer,the product would:
