3. You acquired the following data: bp 173 °C; - Tollens', + iodoform tests; semicarbazone mp 105 °C. You are very confident that your unknown is 2- octanone. Data is spot on, excluding the semicarbazone mp. You suspect the suppressed mp is due to wet crystals. What process or technique (other than continued oven drying) can help you obtain more pure semicarbazone and thus a more accurate mp for comparison? Please write answer in box at right.

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.
