What are \[HC\equiv C-C{{H}_{2}}-C\equiv CH\]\[NaOH\]\[{{104}^{o}}40\] in the following reactions?

(I) \[{{103}^{o}}\]

(II) \[{{107}^{o}}\]

(III) \[{{109}^{o}}28\]

A)

\[\underline{X}\]	\[\underline{X}\]	\[p\pi .d\pi \]
[a] \[Xe{{O}_{3}}\]	\[Xe{{O}_{4}}\]	\[Xe{{O}_{4}}\]

B)

\[\underline{X}\]	\[\underline{X}\]	\[p\pi .d\pi \]
[b] \[\Delta {{H}_{f}}(H)=218kJ/mol\]	\[H-H\]	\[52.15\]

C)

\[\underline{X}\]	\[\underline{X}\]	\[p\pi .d\pi \]
[c] \[911\]	\[104\]	\[52153\]

D)

\[\underline{X}\]	\[\underline{X}\]	\[p\pi .d\pi \]
[d] \[Alkyne\xrightarrow[Lindlars\,\,catalyst]{{{H}_{2}}}A\xrightarrow{Ozonolysis}\underset{only}{\mathop{B}}\,\]	\[\xleftarrow[\Pr ocess]{Wac\ker }C{{H}_{2}}=C{{H}_{2}}\]	\[{{H}_{3}}C-C\equiv C-C{{H}_{3}}\]

Correct Answer: C

Solution :

 I. II. \[C{{H}_{3}}COOH\xrightarrow{{}}6HI\xrightarrow{\operatorname{Re}d\,P}C{{H}_{3}}C{{H}_{3}}+3{{I}_{2}}\] \[+2{{H}_{2}}O\] III.
