Out of O_(2) " and " O_(3) which is a better oxidising agent ?
Si_(2)O_(7)^(6-) anion is obtained when:
(Si_(2)O_(5))_(n)^(2n-) anion is obtained when:
Which of the following statements are correct ? (i) Amongs O_(2),O_(2)^(+),O_(2)^(-) and O_(2)^(2-),O_(2)^(+) has the greatest stability. (ii) Double bond in C_(2) consists of both Pi (pi) bonds because of the presence of four electrons in two pi molecule orbitals. (iii) Amongst B_(2),C_(2),N_(2) and O_(2) , mixing of 2s-2p orbitals takes palace only in N_(2) molecule. (iv) Isoelectronic molecules and ions have identical bond order.
