Vedclass · Answer

(C) Secondary alcohols undergo oxidation to form ketones. For example,$CH_3-CH(OH)-CH_3 \xrightarrow{[O]} CH_3-CO-CH_3$. This statement is correct.$(B)$ Ethanol undergoes dehydration with conc. $H_2SO_4$ at $180\,^{\circ}C$ to yield ethylene $(CH_2=CH_2)$. This statement is correct.$(C)$ Methanol $(CH_3OH)$ does not contain the $CH_3-CH(OH)-$ group,so it does not give the iodoform test. This statement is incorrect.$(D)$ Alcohols react with active metals like sodium to liberate hydrogen gas: $2R-OH + 2Na 	o 2R-ONa + H_2$. This statement is correct.Therefore,statements $(A), (B),$ and $(D)$ are correct.
