Ammonia (NH,) and silane (SiH,) are small molecules,
each of which has four electron pairs in the valence shell
of the central atom. Account for the difference in bond
angle between the two molecules, 107.3° in ammonia and
109.5° in silane.
Sigma bonds can form between different types of orbitals. The main criterion for sigma bond
formation is that the two bonded atoms have valence orbitals with lobes that point directly at
each other along the line between the two nuclei.
The images below show the shapes of two orbitals on adjacent atoms. Choose all of the
combinations that will lead to formation of a sigma bond.

- Does a sulfer-oxygen bond have a significant dipole moment?arrow_forwardThe concept of valence-shell electron-pair repulsion (VSEPR) is presented in introductory organic chemistry as a way to predict molecular geometries. The idea be- hind VSEPR is that areas of electron density repel each other so that the geometry of bonds and/or lone pairs of electrons around any one atom places these areas as far apart as possible. For four areas of electron density, a tetrahedral geometry is predicted. For three areas of electron density, a trigonal planar geometry is predicted. Two areas of electron density lead to a linear geometry. VSEPR is simply a predictive tool, but in some cases, it gives an incorrect prediction. In these instances, additional insights into bonding are necessary, such as resonance. Interestingly, several important situations are critical to biochemistry where VSEPR breaks down. Two examples are shown here. :O: CH3 H,N H3N CH3 H :0: :0: Histidine The circled nitrogen atoms are predicted by VSEPR to be tetrahedral in geometry because each…arrow_forward4.
