Match List - I with List - II.
List - I |
List – II |
(a) PCl5 |
(i) Square pyramidal |
(b) SF6 |
(ii) Trigonal planar |
(c) BrF5 |
(iii) Octahedral |
(d) BF3 |
(iv) Trigonal bipyramidal |
Choose the correct answer from the options given below.
Answer
Correct Answer : a ) (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)
Explanation :PCl5 – Phosphorous Pentachloride- It has a trigonal bipyramidal structure in gaseous and liquid phases. The three P-Cl bonds are equivalent while axial bonds are longer. It is used as a chlorinating reagent.
SF6 – Sulphur Hexaflouride- It is a colorless, odorless, man-made gas consisting of one sulphur and 6 fluoride atoms. It is non-flammable with high chemical stability. It has octahedral structure. It is used as an electric insulator and arc suppressant.
BrF5 – Bromine Pentafluoride- It has square pyramidal structure. It is used in oxygen isotope analysis and as a fluorinating agent in the processing of uranium.
BF3 – Boron Trifluoride - Its molecular geometry is Trigonal Planar. The three BF bonds are at 120° in the same plane. It is a colorless gas with a pungent smell. It is toxic.
Hence, option (A) is correct.
