The suitable reagent for the reduction of C2H5COOH into C3H7OH is

Question

The suitable reagent for the reduction of C2H5COOH into C3H7OH is (A)  BH3/THF and H3O+  (B)  NaBH4  (C)  Na/EtOH  (D)  H2/catalyst

Tardigrade Admin · Accepted Answer

H2/ catalyst, NaBH4 and Na/C2H5OH etc., are weak reducing agent, hence these reduce aldehyde, ketone, alkene etc., groups but these cannot reduce carboxylic acid. Hence, -COOH group is reduced to -CH2OH group by the reaction of BH3/THF and H3O+. underset textpropanoic textacid mathopC2H5COOH xrightarrow[(ii) H3O+](i) BH3/THF underset textpropyl textalcohol mathopC2H5.CH2OH
