To determine which GP Ib-IX-V amino acid sequences are critical for bond formation, we have used optical tweezers to measure forces involved in the binding of vWf to GP Ib-IX-V variants. Inasmuch as GP Ib(alpha) subunit is the primary component in human GP Ib-IX-V complex that binds to vWf, and that canine GP Ib(alpha) , on the other hand, does not bind to human vWf, we progressively replaced ...
A steric number of three leads to the formation of sp2 orbitals. The bond angles depend on the number of lone electron pairs. For example, boron trichloride has no lone pairs, a trigonal planar shape and bond angles of 120 degrees. The trioxygen molecule O3 has one lone pair and forms a bent shape with bond angles of 118 degrees.
A bond of higher bond order also exerts greater repulsion since the pi bond electrons contribute. For example in isobutylene, (H 3 C) 2 C=CH 2, the H 3 C−C=C angle (124°) is larger than the H 3 C−C−CH 3 angle (111.5°). However, in the carbonate ion, CO 2− 3, all three C−O bonds are equivalent with angles of 120° due to resonance ...

For CHCl3, the geometry will be tetrahedral which leads to bond angles of 109.5 degrees. However, taking into account the size of the chlorines vs. the hydrogen, since the chlorines are larger, the ClCCl bond angle will be slightly more than 109.5 degrees, and the HCCl bond angle will then be slightly smaller.
