$H_2 + F_2 \longrightarrow 2HF$

given that
Bond energy of $H-H$ bond $= 434\, kJ/mol$
Bond energy of $F-F$ bond $= 158\, kJ/mol$
Bond energy of $H-F$ bond $= 565\, kJ/mol$

.....$ kJ$

ethyne $\xrightarrow[\begin{smallmatrix} 
 (2)\,\,excess\,I-\,C{{H}_{2}}\,-\,{{(C{{H}_{2}})}_{2}}-\,C{{H}_{3}} \\ 
 (3)\,\,{{H}^{\oplus }} 
\end{smallmatrix}]{(1)\,\,excess\,NaN{{H}_{2}}}$

Statement $I$ : The correct order of first ionization enthalpy values of $\mathrm{Li}, \mathrm{Na}, \mathrm{F}$ and $\mathrm{Cl}$ is $\mathrm{Na}<\mathrm{Li}<\mathrm{Cl}<\mathrm{F}$.

Statement $II$ : The correct order of negative electron gain enthalpy values of $\mathrm{Li}, \mathrm{Na}, \mathrm{F}$ and $\mathrm{Cl}$ is $\mathrm{Na}<\mathrm{Li}<\mathrm{F}<\mathrm{Cl}$

In the light of the above statements, choose the correct answer from the options given below :

$(a)\, B_2H_6 + 6H_2O \to$
$(b)\, B_2H_6 + 6CH_3OH \to$
$(c)\, B_2H_6 + 3Cl_2 \to$
$(d)\, BR_3 + 3CH_3COOH \to$

Identify incorrect statement about product $(s)$
