Question

One mole of diethyl ether on heating with conc. HI gives 

(a) 1 mole of C₂H₅I and-1 mole of C₂H₅OH 

(b) 2 moles of C₂H₅I 

(c) 2 moles of C₂H₅OH 

(d) not definite

Answer 1

(b) 2 moles of C₂H₅I 

One mole of diethyl ether (C₂H₅OC₂H₅) on heating with concentrated HI (hydroiodic acid) undergoes cleavage of the ether linkage to form two moles of ethyl iodide (C₂H₅I).
