Virtual tables are attached to the class not to the instance of class.

yes v table is created but the corresponding entry for pure virtual function will be NULL.
Hence at runtime when we will check if the vtable will have any NULL entries the corresponding class will not be allowed to instantiate

yes

yes.it doest not depend upon where u instantiate it or not

See this: stackoverflow.com/questions/2592438/does-an-abstact-classes-have-a-vtable

Yes, but the vtable pointer to pure virtual function will be NULL.

Yes, as abstract/base class will be constructed when an object of derived class is constructed, hence at that time the abstract/base class constructor will set the vtable pointer to its own vtable.

pure abstract class creates vtable but entry of address to function is not made..which makes vtable incomplete and that makes the class not to create object.

since the object creation is not possible for abstarct class then where exactly the v-table is/are created for the abstract class.

since the object creation is not possible for the abstarct class then where exactly the v-table is/are created...according to me, the v-tables are created in the ctor of the class..right....in this case, what would be the behaviour

Silly question. You cannot instantiate abstract classes, so... No.
