For a molecule with the formula ab2, the molecular shape is for a molecule with the formula ab2, the molecular shape is linear or t-shaped trigonal planar linear or bent linear or trigonal planar t-shaped

linear or trigonal planar

Explanation:

The molecular formula AB have the following criteria:

A= the central atom

B= directly bonded atoms.

In Molecular Geometry, Molecular Formula ABcan either be Linear or Trigonal Planar.

In linear geometry, they are formed as a result of Sp hybridised orbital. Sp hybridised orbital involves blending of one s-orbital and one p-orbital to produce a hybrid orbital directed along a straight line, therefore making it linear e.g CO , HCN etc.

In Trigonal Planar, they are formed as a result of Sp hybridised orbital. Sp hybridised orbital are formed by mixing of one s-orbital and two p-orbitals to produce orbitals which are coplanar and the lobes directed towards the corners of an equilateral triangle. (Trigonal Planar) e.g BF , , SO etc.

idk i’m struggling too

the answer is definitely c.
