Coronal mass ejections associated with eruptive prominences often display a classical 3-part structure in white light, viz., a bright leading edge followed by a dark cavity devoid of material and an embedded prominence or core. However, the initiation of such CMEs and nature of their acceleration as they propagate outward in the corona are some of the basic questions that remain unsolved. In particular, the question of role of the prominence in triggering or driving the CME has not been settled yet. In this paper, we report observations of coronal mass ejections (CMEs) associated with eruptive quiescent prominences that occurred on June 2,1998 and June 21-22, 1998. A comparative study based on multi-wavelength observations is presented. Various features in three part structured, white-light CME as observed by LASCO C2 and C3 coronagraphs aboard SOHO were compared with features in other wavelengths, for example, in FeXIV green and FeX red emission lines by LASCO-C1 coronagraph. These observations were combined with other data-sets in H-alpha, X-ray and radio wavelengths. The comparison provides an important clue to the understanding, the origin or the initiation of the CMEs. Measurements of speed and acceleration of these CMEs have also been made in order to understand the nature of propagation of the CMEs in the outer corona and the driver that triggers the onset of the CMEs.
