What happens when

(write chemical equation in each case)

(a) ethanol is burnt in air?

(b) ethanol is heated with excess conc. \[{{H}_{2}}S{{O}_{4}}\] at 443 K?

(c) a piece of sodium is dropped into ethanol?

 

Answer:

(a) \[C{{H}_{3}}C{{H}_{2}}OH+3{{O}_{2}}\xrightarrow{Air}2C{{O}_{2}}+3{{H}_{2}}O+Heat+light\]

(b) \[C{{H}_{3}}C{{H}_{2}}OH\xrightarrow{Conc.{{H}_{2}}S{{O}_{4}}}C{{H}_{2}}=C{{H}_{2}}+{{H}_{2}}O\]

(c) \[2C{{H}_{3}}C{{H}_{2}}OH+2Na\to 2\,C{{H}_{3}}C{{H}_{3}}ONa+{{H}_{2}}\]
