The boiling point of alcohols is $....$ than corresponding thiols.

$A$ substance $C_4H_{10}O$ yields on oxidation a compound $C_4H_8O$ which gives an oxime and a positive iodoform test. The original substance on treatment with conc. $H_2SO_4$ gives $C_4H_8$. The structure of the compound is:

Consider the following reaction sequence: $CH_3CHO$ $\xrightarrow[(ii) H_2O/H^+]{(i) CH_3MgBr} (A)$ $\xrightarrow{H_2SO_4, \Delta} (B)$ $\xrightarrow[(ii) H_2O_2/OH^-]{(i) B_2H_6} (C)$. $(A)$ and $(C)$ are

The correct order of decreasing reactivity towards $H_3PO_4$ for the following compounds is:

Ethyl alcohol is heated with conc. $H_2SO_4$. The product formed is

$1 \ mol$ of alcohol reacts with $Na$ to produce what weight of hydrogen (in $g$)?
