4. Which of the following is LINEAR TRIATOMIC?

A.        
B.         
C. 
D.              
E.          
F.

Explanation

linear means straight line. this shape forms a straight line, there for its LINEAR. because of the number of atoms it has, it makes it TRIatomic, (Tri is a prefix for three)

5. Which of the following is a TETRAHEDRAL?

A.        
B.         
C. 
D.              
E.
