In the reaction sequence, `"Ethane" overset("HOCl") to A overset(x) to "ethane" -1,2-diol`. A and X respectively are

Options

A. Chloroethane and NaOH
B. ethanol and `H_(2)SO_(4)`
C. 2 - chloroethan -1- ol and `NaHCO_(3)`
D. ethanol and `H_(2)O`

Answer

C

Explanation

Hint : `CH_(2)=CH_(2)overset(HOCl)rarrunderset(OH)underset("| ")(CH_(2))underset("Cl ")underset("| ")(CH_(2))-overset(overset("(X)")(NaHCO_(3)))underset(underset(-CH_(2))(-NaCl))rarr overset(HOCl)rarrunderset(OH)underset("| ")(CH_(2))underset("Cl ")underset("| ")(CH_(2))`
