QAIPM-2012-Ch-1630: NEET 2012 Chemistry - Class 11 AIPM-2012-Ch-1630 Solution: Four diatomic species are listed below. Identify the correct…

Four diatomic species are listed below. Identify the correct order in which the bond order is increasing in them NO<O2−<C22−<He2+NO < O_2^- < C_2^{2-} < He_2^+ O2−<NO<C22−<He2+O_2^- < NO < C_2^{2-} < He_2^+ C22−<He2+<O2−<NOC_2^{2-} < He_2^+ < O_2^- < NO He2+<O2−<NO<C22−He_2^+ < O_2^- < NO < C_2^{2-}

Multiple Choice Options

  • A NO &lt; {O_2}^ - &lt; {C_2}^{2 - } &lt; He_2^ + NO < O 2 _ _ < C 2 _ 2 _ < H e 2 + _
  • B {O_2}^ - &lt; NO &lt; {C_2}^{2 - } &lt; He_2^ + O 2 _ _ < NO < C 2 _ 2 _ < H e 2 + _
  • C {C_2}^{2 - } &lt; He_2^ + &lt; {O_2}^ - &lt; NO C 2 _ 2 _ < H e 2 + _ < O 2 _ _ < NO
  • D He_2^ + &lt; {O_2}^ - &lt; NO &lt; {C_2}^{2 - } H e 2 + _ < O 2 _ _ < NO < C 2 _ 2 _

Step-by-Step Verified Solution

Diatomic species | Bond order NO | 2.5 O 2 _ | 1.5 C 2 2 _ | 3.0 H e 2 + | 0.5 The increasing order: H e 2 + < O 2 _ < N O < C 2 2 _
