Consider the best Lewis structure for the molecule HCN, where carbon is the central atom and hydrogen and nitrogen are bonded to carbon. Fill in the following information about the structure.Note: Concerning the first 3 blanks, answers should be given as the number of lone‑pair electrons. For example, if there is one lone pair, enter 2 because a lone pair consists of two electrons. The number of lone-pair electrons (Lewis dots) on H is: [H-electrons].The number of lone-pair electrons (Lewis dots) on C is: [C-electrons].The number of lone-pair electrons (Lewis dots) on N is: [N-electrons].The number of bonds (lines) between the H and C atoms is: [HC-bond].The number of bonds (lines) between the C and N atoms is: [CN-bond].

Recall that in organic compounds, there are often many hydrogens attached to carbon atoms, so they are typically omitted in bond‑line structures. How many hydrogen atoms are bonded to the indicated carbons in the Vitamin D₃ molecule? Carbon 1 is bonding to [1] hydrogen(s).Carbon 2 is bonding to [2] hydrogen(s).Carbon 3 is bonding to [3] hydrogen(s).
