Which is the most reasonable prediction for the H–C–H bond angle in CH4? Select one: a. 90° b. 109.5° c. 120° d. 107° e. 105°
Why is the H–N–H angle in NH3 smaller than the H–C–H bond angle in CH4? The electron-pair geometry for NH3 is tetrahedral. with ______ bonding pair(s) of electrons and ______ lone pair(s) of electrons. A lone pair takes up more room than a single bond, causing the H–N–H angle to be smaller than the bond angle in a regular tetrahedron such as CH4. Why is the H–N–H angle in NH4+ identical to the H–C–H bond angle in CH4? The electron-pair...
