Hybridization of atomic orbitals

At room temperature hydrogen cyanide is a liquid that evaporates readily, whereas ethyne, $\ce{C2H2}$, which has almost the same molar mass, is a gas that boils at −84 °C. (i) Draw the Lewis formula of the hydrogen cyanide molecule, showing all valence…

(i) Draw the Lewis formula of buta-1,3-diene. (ii) State the hybridization of the carbon atoms in buta-1,3-diene.

Methanoic acid, $\ce{HCOOH}$, has the structure shown. What are the hybridizations of the carbon atom, the oxygen atom of the C=O bond and the oxygen atom of the O–H bond? In each option the hybridizations are listed in that order. A. $\mathrm{sp^2}$,…

Which hybridization is shown by the carbon atom and by the nitrogen atom in hydrogen cyanide, $\ce{HCN}$? A. C: $\mathrm{sp}$, N: $\mathrm{sp}$ B. C: $\mathrm{sp}$, N: $\mathrm{sp^2}$ C. C: $\mathrm{sp^2}$, N: $\mathrm{sp}$ D. C: $\mathrm{sp^2}$, N:…

Which orbitals overlap to form the $\sigma$-bond and the two $\pi$-bonds between carbon and nitrogen in hydrogen cyanide, HCN? A. $\sigma$-bond: sp and $\mathrm{sp^3}$; $\pi$-bonds: p and p B. $\sigma$-bond: sp and sp; $\pi$-bonds: p and p C. $\sigma$-bond: sp…

What is the hybridization of the atoms labelled I, II and III in the molecule shown? A. I: $\mathrm{sp}$, II: $\mathrm{sp^3}$, III: $\mathrm{sp^3}$ B. I: $\mathrm{sp}$, II: $\mathrm{sp^2}$, III: $\mathrm{sp^3}$ C. I: $\mathrm{sp^2}$, II: $\mathrm{sp^3}$, III:…

A computer simulation models what happens when small pieces of lithium and of sodium are dropped into water. For each metal five pieces of increasing mass are used, the same set of masses for both metals, and the simulation records how long each piece takes to…
