    Which will give chiral molecule?

    A)  \[C{{H}_{3}}COCl\xrightarrow{LiAl{{H}_{4}}}\]

    B)  \[{{C}_{2}}{{H}_{5}}CHO\xrightarrow[{{H}^{+}}/{{H}_{2}}O]{C{{H}_{3}}MgBr}\]

    C)   \[{{(C{{H}_{3}})}_{2}}CH{{C}_{2}}{{H}_{5}}\xrightarrow{Cu}\]

    D)  

    Correct Answer: B

    Solution :

                      Propionaldehyde give chiral molecule on reaction with Grignard reagent In resulting product C* is an asymmetric carbon atom as all the four valencies are satisfied with four different atoms or groups.
