  We report the observational findings of the Sh2-112 H{\sc ii} region by using
the multiwavelength data analysis ranging from optical to radio wavelengths.
This region is powered by a massive O8V-type star BD +45 3216. The surface
density distribution and minimum spanning tree analyses of the young stellar
object (YSO) candidates in the region reveal their groupings toward the western
periphery of the H{\sc ii} region. A GMRT radio continuum emission peak is
found toward the north-west boundary of the H{\sc ii} region and is
investigated as a compact/ultra-compact H{\sc ii} region candidate powered by a
B0-B0.5 type star. Toward the south-west direction, a prominent curved rim-like
structure is found in the H$\alpha$ image and GMRT radio continuum maps, where
the H$_2$ and $^{13}$CO emission is also observed. These results suggest the
existence of the ionized boundary layer (IBL) on the surface of the molecular
cloud. This IBL is found to be over-pressurized with respect to the internal
pressure of the surrounding molecular cloud. This implies that the shocks are
propagating/ propagated into the molecular cloud and the young stars identified
within it are likely triggered due to the massive star. It is also found that
this region is ionization bounded toward the west-direction and density bounded
toward the east-direction. Based on the distribution of the ionized gas,
molecular material, and the YSO candidates; we propose that the Sh2-112 H{\sc
ii} region is a good candidate for the blister-type H{\sc ii} region which has
been evolved on the surface of a cylindrical molecular cloud.
