A) \[{{104}^{o}}40\]
B) \[{{103}^{o}}\]
C) \[{{107}^{o}}\]
D) \[{{109}^{o}}28\]
Correct Answer: C
Solution :
Paramagnetic property depends upon the number of unpaired electrons. Higher the number of unpaired electrons, higher the paraitlagnetic property will be. \[HC\equiv C-C{{H}_{2}}-C\equiv CH\], no. of unpaired electrons = 1 \[NaOH\] no. of unpaired electrons = 3 \[{{104}^{o}}40\], no. of unpaired electrons = 4 \[{{103}^{o}}\], no. of unpaired electrons = 5 Hence, correct order is \[{{107}^{o}}\]
