Question

Which of the following molecule has no dative bond

Answer 1

Since there are no examples given in the question, so it might be assumed that a general reference of dative bond is required in this answer.

Dative bonds are also popular by other names called the coordinate covalent bond or simply a coordinate bond.

It has 2 center form of bond where there are 2 electrons and these are brought up from the same atom itself.

So each atom has to give one electron  in order to make this possible in such a bonding as both are electrons are drawn from the same atom.

So there is a characteristic of sharing of electrons.
