| (I) Bond orders of \[CO\]and \[C{{O}^{\oplus }}\] are 3 and \[3.5\] respectively. |
| (II) \[CO\]molecule is diamagnetic and \[C{{O}^{\oplus }}\]ion is paramagnetic with \[{{\mu }_{MM}}=\sqrt{8}\,BM.\]. |
| (III) \[CO\](g) is prepared by dehydration of formic acid with cone. \[{{H}_{2}}S{{O}_{4}}\] at\[373\text{ }K\]. |
| (IV) Mixture of \[CO(g)+{{H}_{2}}(g)\] is called water gas, whereas mixture of \[CO(g)+{{N}_{2}}(g)\] is called synthesis gas. |
A) I, II
B) II, III
C) I, III
D) II, IV
Correct Answer: C
Solution :
[c] Statement (I) is CORRECT Statement (II) is INCORRECT CORRECT statement:- \[C{{O}^{\oplus }}\] ion is paramagnetic with one unpaired \[\bar{e},\] with \[{{\mu }_{MM}}=\sqrt{3}\,BM.\]. Statement (III) is CORRECT:- \[\underset{Formic\,\,acid}{\mathop{HCOOH}}\,\,\xrightarrow[373K]{{{H}_{2}}S{{O}_{4}}}CO+{{H}_{2}}O\] Statement (IV) is INCORRECT CORRECT statement:- Mixture of \[CO(g)+{{N}_{2}}(g)\] is called producer gas
