Dear Aspirants,
This is the third set of problems for JEE Mains 2013. The level is Advance, questions may be tough for some students. Have patience and be committed towards your goal.
Try to solve it completely for better revision of concepts before exam. I wish you all the best for exam on Sunday.
I'll be releasing "detailed solutions of JEE Mains" paper on Sunday just after exam, so be in regular touch with updates of this blog.
Best of luck...

Delete@all- as the compound is having 2 carbonyl group the metal will provide 1 electron each to both of them and a pinacol will be formed first which will rearrange to a pinacolone in presence of acid. After pinacolone's normal reduction you will get your unexpected product... If still you are not getting it than let me know...
