Dot diagrams are almost impossible here in text, with hard carriage returns. Sorry.
No worries! I can still explain how to draw the Lewis dot structures for the given molecules and ions you provided. Please note that I'll describe the general approach, but due to the limitations of text, I won't be able to provide the specific structure for each one. Let's get started:
1. CH3CCH (Propyne): Start by determining the total number of valence electrons. Then, arrange the atoms in the molecule, connecting them with single bonds. Distribute the remaining electrons around the atoms, giving each atom an octet (except hydrogen, which only needs two electrons).
2. FNO (Nitrosyl fluoride): Once again, count the total number of valence electrons. Place the least electronegative atom (F) in the center, surrounded by the other atoms (N and O). Connect the atoms with single bonds. Distribute the remaining electrons, giving each atom an octet (hydrogen only needs two electrons).
3. N2H4 (Hydrazine): Similar to the previous examples, count the total number of valence electrons. Place the least electronegative atom (N) in the center, surrounded by the other atoms. Connect the atoms with single bonds. Distribute the remaining electrons, giving each atom either an octet (except hydrogen, which again only needs two electrons).
4. PCl5 (Phosphorus pentachloride): Determine the total number of valence electrons. Place the least electronegative atom (P) in the center, surrounded by the chlorine atoms (Cl). Connect the atoms with single bonds. Distribute the remaining electrons, giving each atom an octet (except hydrogen).
5. CH3OH (Methanol): Count the total number of valence electrons, and draw the structure of the molecule with carbon (C) in the center, connected to the hydrogen (H) atoms and the oxygen (O) atom by single bonds. Distribute the remaining electrons, giving each atom an octet (except for hydrogen).
6. OH- (Hydroxide): Start by counting the total number of valence electrons. The oxygen (O) atom takes the central position, and the hydrogen (H) atom is attached as a single bond. Place the remaining electrons as a lone pair on the oxygen atom.
I hope this gives you a general idea of how to approach drawing Lewis dot structures for these molecules and ions. If you need further assistance with any specific molecule, feel free to ask!
