Get started for freeWhich one of the following statements is true about \(\mathrm{BeH}_{2} ?\) (a) It is ionic with \(\mathrm{H}\) as the anion. (b) It is ionic with \(\mathrm{H}\) as the cation. (c) It has polar covalent bonds with a partial negative charge on \(\mathrm{H}\). (d) It has polar covalent bonds with a partial positive charge on \(\mathrm{H}\).
Which one of these four molecules contains a triple bond: \(\mathrm{F}_{2}, \mathrm{O}_{3}, \mathrm{HCN}\), or \(\mathrm{H}_{2} \mathrm{CO}\) ?
Draw a dot diagram for \(\mathrm{PF}_{5} .\) Which atom is an expanded octet atom?
Draw a dot diagram for \(\mathrm{BrF}_{5}\). (Hint: \(\mathrm{Br}\) is an expanded octet atom in this molecule. Don't be afraid to stick lone pairs of electrons on it if you have to.)
Hydrogen isothiocyanate has formula HNCS, and its atoms are connected in the order written. Draw dot diagrams showing all the valid resonance forms.
