abhishek , I don't think so , I think we get 2-methylprop2-en-1-ol.

H2SO4 acts as a dehydrating agent not as an oxidising agent .

protonation of the 2o takes place . this leads to the formation of the stable 2o carbocation.

then H+ is eliminated form one of the methyl gps. giving the product.

What i thought was that in the presence of H+ pinacol/Pinacolone rearrangement will be there.............

shouldn't the product be 2-methyl propanaldehyde. ? I got a doubt. the stable 2o carbocation is formed , then hydride shift . this is more easier remember ? thus getting teh above product.
