Question

Find the number of statements in which "n" must be odd number

(i) $XX_{n}^{1}$ interhalogen compound.

(ii) Highest oxidation number of $M^{+ n}$ of N-family

(iii) $HXO_{n}$ halic acid

(iv) Oxide of nitrogen $N_{m} O_{n}$ which is mix anhydride

(v) $H_{2} S (n) O_{6}$ polythionic acid

(vi) Number of fluorine in xenonoxyflouride $(XeO_{m} F_{n})$

(vii) Number(n) of nodal plane in each B.M.O. $(π)$ of $O_{2}$

(i) Interhalogen compounds X X n ′ ​ have n = 1 , 3 , 5 , 7 . These are all odd numbers. (ii) Highest oxidation number of N-family is +5. So n = 5 , which is odd. (iii) Halic acids H X O n ​ include H Cl O 3 ​ ( n = 3 ), H B r O 3 ​ ( n = 3 ), H I O 3 ​ ( n = 3 ). Here n = 3 , which is odd. (iv) Mixed anhydride of nitrogen is N 2 ​ O 3 ​ (anhydride of H N O 2 ​ ) and N 2 ​ O 4 ​ (anhydride of H N O 2 ​ and H N O 3 ​ ). N 2 ​ O 3 ​ has n = 3 (odd), N 2 ​ O 4 ​ has n = 4 (even). So this statement does not always require n to be odd. (v) Polythionic acids H 2 ​ S n ​ O 6 ​ have n ≥ 2 . n can be even or odd. (vi) Xenon oxyfluorides X e O m ​ F n ​ include X e O F 4 ​ ( n = 4 ), X e O 2 ​ F 2 ​ ( n = 2 ), X e O 3 ​ F 2 ​ ( n = 2 ). n is even. (vii) Number of nodal planes in π BMO of O 2 ​ is 1 (odd). Statements (i), (ii), (iii), and (vii) require n to be an odd number. Thus, there are 4 such statements.
