We present here the recent results on two distant Galactic H II regions,namely NGC~2282 and Sh2-149, obtained with multiwavelength observations. Ouroptical spectroscopic analysis of the bright sources have been used to identifythe massive members, and to derive the fundamental parameters such as age anddistance of these regions. Using IR colour-colour criteria andH$_\alpha$-emission properties, we have identified and classified the candidateyoung stellar objects (YSOs) in these regions. The $^{12}$CO(1-0) continuummaps along with the {\it K}-band extinction maps, and spatial distribution ofYSOs are used to investigate the structure and morphology of the molecularcloud associated with these H II regions. Overall analysis of these regionssuggests that the star formation occurs at the locations of the denser gas, andwe also find possible evidence of the induced star formation due to thefeedback from massive stars to its surrounding molecular medium.
