Question

what is unhybridised orbitals? And how to determine them?

Answer 1

or if the atom has more than three valence electrons in its outer shell three of the electron orbitals hybridize and one of the p orbitals remainsunhybridized: It is the unhybridized porbitals that then form pi bonds for double bonding: Now let's look at sp hybridization: Again there are two ways to form sp hybrids.
