    Dehydration is removal of water.

    In alcohols dehydration is α-β elimination or 1,2 elimination, it means the hydroxyl group will be removed from α-carbon while the hydrogen will be removed from near by carbon.

    In case of neopentyl alcohol there is no β hydrogen present on the β carbon [as shown in figure].

    The only possible way for it to undergo dehydration is by rearrangement.

    The process or mechanism can be understood as:

    so the chief product is 2-methylbut-2-ene
