In the following NaCl type structure :

Salt Anium-anion Cation-anion

distance distance

MT 2.40 A0 1.70 A0

MQ 1.63 A0 1.15 A0

RT 2.66 A0 1.88 Aº

RQ 2.09 A0 1.48 Aº

MT is represented as :

A

B

C

D

Answer

Explanation

Solution

The difference in internuclear distance between MT and RT indicates that the cations must not be touching all the anions in MT. Thus the structure of MT is
