A Lewis structure is a two-dimensional representation of a molecule that does not necessarily show what shape that molecule would take in three dimensions. From the given Lewis structure and what you know about VSEPR theory, identify the shape of the molecule. A molecule with atom Y single bonded with 2 X substituents. The Y atom has two lone pairs.

Orbital geometry is Tetrahedral

Molecular geometry is Bent/V shape

Explanation:

Using the VSEPR theory which states that

The shape of a molecule depends upon the number of valence shell electron pairs  (bonded or nonbonded) around the central atom. Pairs of electrons in the valence shell repel  one another since their electron clouds are negatively charged. These pairs of electrons tend to occupy such positions in space that minimize  repulsion and thus maximize distance between them. The valence shell is taken as a sphere with  the electron pairs localizing on the  spherical surface at maximum distance  from one another. A multiple bond is treated as if it is a single  electron pair and the two or three electron  pairs of a multiple bond are treated as a single super pair. Where two or more resonance structures  can represent a molecule, the VSEPR  model is applicable to any such structure

so we have Y as the central atom and it has 2X substituents on its either sides with two lone pairs on Y. This is a case of Y which has

2 bonds with X on either sides

2 lone pairs on Y

The orbital geometry will be Tetrahedral but its Molecular geometry will be Bent/V shaped

The formula of the compound will be YX2
