Chemistry The Solid State MHT CET

Not in JEE Main or NEET syllabus

Match the following. Column I (Cell parameters) | Column II (Crystal type) A. a=b=c=90° | p. Hexagonal B. (blank in source) | q. Cubic C. a=b≠c | r. Rhombohedral D. a=b= ≠90° | s. Tetragonal

(A)A–q,r; B–q,s; C–p,s; D–rCorrect
(B)A–q; B–s,p; C–p,r; D–r,s
(C)A–q,p; B–p; C–s,q; D–s
(D)A–r,s; B–s,q; C–p,s; D–s

Answer: (A)

Solution

Cubic (q) has a = b = c with α = β = γ = 90°, tetragonal (s) and hexagonal (p) both have a = b ≠ c, and rhombohedral (r) has a = b = c with α = β
