The synonym for water gas when used in the production of methanol is:

Consider the following reaction :

$2{\mathrm{HSO}}_4^{-}\left(\mathrm{aq}\right)\frac{\left(1\right) \mathrm{Electrolysis}}{\left(2\right) \mathrm{Hydrolysis}}2{\mathrm{HSO}}_4^{-}+2{\mathrm{H}}^{+}+\mathrm{A}$

The dihedral angle in product $\mathrm{A}$ in its solid phase at $110 \mathrm{K}$ is
