Greater the overlap of the orbitals, _________________________

• lesser the bond strength

• greater the bond strength

• bond strength remains the same

• no bond formation

s-s overlap is a _______

•  $\sigma\ Bond$

   

•  $\pi\ Bond$  

VSEPR theory is used to predict

• the number of unshared pairs of electrons in a Lewis structure.

• the number of multiple bonds in a Lewis structure.

• the three-dimensional geometry of a molecule.

• the three-dimensional crystal lattice structure of ionic compounds.

Any molecule with only two atoms must be linear. Three-atom molecules such as BeCl₂ can also be linear. For linear molecules, the bond angle is

• $360\degree$

• $180\degree$

• $120\degree$

• $90\degree$

Which molecule would have this molecular geometry?

• BF₃
• CH₄
• PCl₅
• CO₂
