AP还会出一些选择题来考察这个知识点,除了直截了当地问你geometry,还可能问bond angles或者hybridization。 【例题】 官方不会放选择题真题,所以我为大家编写了两个小问题,大家可以感受一下~(但比较基础)。答案和解析依旧在最后~ 1.What is the bond angle of CH4? A)180 B)120 C)109.5 D)90 2. What is ...
* triple bond angle 180° (± 0.5 rad): check_angle1 * double bond angle 120° or 180° (± 0.5 rad): check_angle2 * sp 2 atom's bond angles 120°: check_angle3 * sp 3 atom's bond angles 90° or 3 bond angles 120°, 4th bond of an angle of n times 15°; or a bond...
Results of minimum basis SCGF calculations on H 2O are reported for seven different HOH angles from 90 to 120掳. Optimum hybridization is nearly constant over the range of bond angles considered, thus suggesting the existence of "bent bonds" for all but the equilibrium bond angle, where bond...
But this flat drawing only works as a simpleLewis Structure(video). Once you understand hybridization, you WILL be expected to predict the exact shape (Molecular vs Electronic Geometry, to be discussed shortly) as well as the bond angle for every attached atom. So let’s dig a bit deeper....
fact that according toBent‘s rule,the C-F bond gains p-orbital character leading to high s-character inthe C-H bonds and H-C-H bond angles approaching that of sp2orbitals e.g. 120° leaving less for the F-C-H bond angle. The difference is again explained in terms of bent bonds....
Bond angle is the angle formed by two bonds in a molecule in its molecular geometry. The bond angle can be predicted from the hybridization and the molecular geometry of the molecule.Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View...
These two orbitals overlap with p-orbitals from two O atoms, forming a linear molecule with a bond angle of 180 degrees. ○ The remaining 2py- and 2pz-orbitals on C used for π bonding are at right angles to the bond, and overlap sideways with p-orbitals on the O atoms at either ...

Sp Hybridization The simplest hybrid orbital is sp, corresponding to a steric number of two. The bond angle is linear, or 180 degrees, when the atom has no lone electron pairs. An example is carbon dioxide. Conversely, a nitrogen molecule has one lone electron pair. This gives it a linear...
The shape of a molecule and the bond angles are determined mainly by the hybridization of the central atom. If there are lone pair on the central atom, then the bond angle of molecule can differ from the angles predicted by hybridization. Answer and Explanation: Become a Study.com mem...
