The Tramadol has been a major topic on this site, some good, some bad, and seems almost everyone has an opinion about it one way or the other. My pm dr. gave me some sample of Lyrica which ( besides the weight gain ), it works very well for the nerve pain. It helps me sleep as well.
Trigonal pyramidal molecular geometry. In chemistry, a trigonal pyramid is a molecular geometry with one atom at the apex and three atoms at the corners of a trigonal base, resembling a tetrahedron (not to be confused with the tetrahedral geometry). When all three atoms at the corners are identical, the molecule belongs to point group C3v.
Trigonal planar and trigonal pyramidal are two geometries we use to name the three dimensional arrangement of atoms of a molecule in the space. There are other types of geometries. Linear, bent, tetrahedral, octahedral are some of the commonly seen geometries.ince the lone pair-bond repulsion is greater than the bond â bond repulsion, the bonded three atoms and the lone pair will be far apart as possible. The angle between the atoms will be less than the angle of a tetrahedron (109 o). Typically the angle in a trigonal pyramid is about 107 o.
