Interhalogen compounds have the compositions XX', XX'₃, XX'₅ and XX'₇, where X is the halogen of larger size. For the following interhalogen compounds find the value of (x + y), where x = number of compounds that are SOLID at 298 K and y = number of compounds in which the central atom carries exactly two lone pairs.
ClF, ICl, IBr, ClF₃, BrF₃, IF₇
Answer:
4
Solution:
States at 298 K : ClF(g), ICl(s), IBr(s), ClF₃(g), BrF₃(l), IF₇(g) → x = 2 (ICl, IBr). Lone pairs on the central atom : ClF 3, ICl 3, IBr 3, ClF₃ 2, BrF₃ 2, IF₇ 0 → y = 2 (ClF₃, BrF₃). x + y = 4.
