| Assertion: CsCl has body-centred cubic arrangement. |
| Reason: CsCl has one \[C{{s}^{+}}\] ion and 8 \[C{{l}^{-}}\] ions in its unit cell. |
A) Assertion and reason both are correct statements and reason is correct explanation for assertion.
B) Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C) Assertion is correct statement but reason is wrong statement.
D) Assertion is wrong statement but reason is correct statement.
Correct Answer: A
Solution :
CsCl has body-centred cubic arrangement in which atoms are present at the corners and at the body center. Now, is \[C{{s}^{+}}\]is present at the body centre while \[C{{l}^{-}}\] ions are present at the corners. So, number of \[C{{l}^{-}}\]ions=8 Number of \[C{{s}^{+}}\]ion=1
