Methane is tetrahedral, that is it fits inside a cube with the carbon atom at the intersection of any two diagonals, which is at the......

(a) Write down the Hiickel secular determinant for the four C-atoms of cyclobutadiene in terms of x, where x = (α – E)/ β. (b)......

As vectors have magnitude and direction, the first thing to decide is the direction of the dipole. The electric dipole moment (or just dipole moment)......

It is possible to arrange molecules so that the bond dipoles all point in a particular direction. Below Figure shows the alignment of carbonyl bonds......

A time of flight (TOF) mass spectrometer is sketched below- The TOF MS is all under a vacuum. A pulsed laser fires a pulse of......

The magnitudes of the four hydrogen halide dipoles are given below. Firstly, using vector notation, express the magnitudes of the HF, HBr and the HI......
