Question

Compound x on heating with excess concentrated sulphuric acid at 443 kelvin gives an acid gives unsaturated compound y x also reacts with sodium metal to amol colourless classify and explain the confusion reaction of formation of y and also write the role of sulphuric acid reaction

Answer 1

heating ethanol at 443K with excess concentrated sulphuric acid results in the dehydration of ethanol to give ethene-

CH3-CH2OH→CH2=CH2+H2O

the concentrated sulphuric acid can be regarded as a dehydrating agent which removes water from ethanol.

X-ethanol(CH3CH2OH)

Y-ethene(CH2=CH2)

x reacting with sodium metal:

CH3CH2OH+2Na→2CH3CH2Na+H2
