Swaraj..(CH3)2CMgBr..something is missing here..i mean the valency of cabon shud be 4..which is not here..plz edit it..
and the first compound is a ketone so the alkyl part of Grignard reagent will be attached to ketonic carbon..and OMgBr is formed..then if u add water then tertairy alcohol will be formed...

the answer to ur question is
[(CH3)2 CH]3-C-OMgBr

without hydrolysis. after hydrolysis it will form [(CH3)2 CH]3-C-OH.

IN G.R. BOND BETW. R-Mg IS POLAR SO R DEVELOPS A PARTIAL -VE CHARGE AND Mg DEVELOPS A PARTIAL +VE CHARGE.
SO THE R GROUP ATTACKS THE CARBONYL CARBON.

dont you guys think that steric hindrance is a bit too high here??

As per this, the starting ketone itself is the end product because it is sterically hindered.
