Options
- AA(III), B(IV), C(I), D(II)
- BA(III), B(I), C(II), D(IV)
- CA(III), B(II), C(I), D(IV)
- DA(III), B(IV), C(II), D(I)
Correct answer
C. A(III), B(II), C(I), D(IV)
Step-by-step solution
The molecular geometry of H 3 O + is pyramidal. It consists of three hydrogen atoms bonded to the central oxygen atom, with one lone pair of electrons on the oxygen atom. The acetylide ion consists of two carbon atoms bonded together by a triple bond ( C ≡ C ) with a lone pair of electrons on the terminal carbon atom. So it is linear. The   NH 4 +   ion consists of a central nitrogen atom bonded to four hydrogen atoms. It is tetrahedral. The ClO 2 - ion is bent in shape due to its molecular geometry
