A) 9.8g of an alcohol A completely reacts with an excess of sodium , and a gas is released. When the reaction ceases the volume of the gas is 1.6L measured at a temperature of 22ºc and under a pressure of 1 bar.

Question

A) 9.8g of an alcohol A completely reacts with an excess of sodium , and a gas is released. When the reaction ceases the volume of the gas is 1.6L measured at a temperature of 22ºc and under a pressure of 1 bar.
 a- What gas is released in this reaction, how can it be identified?
 b- Write the equation of thr reaction of alcohol with sodium .
 c- Find the molecular formula of A.

B) The dehydration of alcohol A upon heating and in the presence of sulfuric acid produces only two compounds B and C. Only the molecule of C contains an oxygen atom. The relative density of B with respect to air equals 1.93.
 a- Determine the molecular formulas of the compounds B and C.

THANKS VERY MUCH 4 YOUR HELP!
