Consider the C_(2) molecule in terms of molecular orbital theory and answer the following questions. The \sigma _(2s) orbital of C_(2) is higher in energy than the 2s orbital of C. True False For C_(2) in its ground electronic state, the \sigma _(2p) orbital is the highest occupied molecular orbital (HOMO). True False The \pi _(2p) orbital is...
