Why does CS2 have higher boiling point than OCS (C as

WebThe boiling point and boiling point range have been used as criteria in confirming both the identity and purity of a substance. For example, if we synthesized a known liquid that boiled at 120-122 °C, this value could be used to confirm that we prepared what we were interested in and that our substance was reasonably pure.
