Question

Identify 'B' in the following series of reactions.

\[\ce{Ethanol ->[NaBr][H2SO4, \Delta] A ->[Mg][Dry ether] B}\]

विकल्प

• Ethyl magnesium bromide

• Ethene

• Sodium ethoxide

• Ethyl bromide

Answer 1

Ethyl magnesium bromide

Explanation:

\[\ce{\underset{Ethanol}{CH3 - CH2 - OH} ->[NaBr][H2SO4, \Delta] \underset{\underset{(A)}{Bromoethane}}{CH3 - CH2 - Br} + H2O ->[Mg][Dry ether] \underset{\underset{(B)}{Ethyl magnesium bromide}}{CH3 - CH2 - Mg - Br}}\]
