JAMB Chemistry 2020 Objective — Question 8

Question 8 of 40 from the Joint Admissions and Matriculation Board (JAMB) Chemistry 2020 Objective paper, with the correct answer and a full explanation.

8. i. BeCl2 - Linear ii. H2O - Linear iii. BF3 - Trigonal Planar iv. CH4 - Tetrahedral v. NH3 - Trigonal Planar. Which of the above is correct?

A. A. i, ii, and iii
B. B. ii, iii, and iv
C. C. i, iii and ivCorrect
D. D. i, ii and v

Explanation

BeCl2 is linear, BF3 is trigonal planar, CH4 is tetrahedral — these are correctly matched (i, iii, iv). H2O is actually bent/angular (not linear) and NH3 is pyramidal (not trigonal planar), so ii and v are incorrect.
