The structure has a six-carbon ring which is represented by a hexagon and it includes 3-double bonds. The carbon atoms are represented by a corner that is bonded to other atoms. Benzene Ring Structure Step 1) Obtain the Lewis dot structure for the molecule. Step 2) Draw dipoles for each bond. Dipole arrows point towards the more electronegative element. I draw a dipole pointing towards fluorine.

Looking at the structure, it was easy to say that the other bond must have been hydrogen bond. Hydrogen bonds don't require orbital overlap between the two concerned atoms, they are more of electrostatic interactions caused by the difference in electronegativity. $\endgroup$ – Arishta Dec 10 '16 at 9:09

Kate Petersen Publications Math Papers: (with C. D. Sinclair) Equidistribution of Elements of Norm One in Cyclic Extensions. Upon quotienting by units, the elements of norm 1 in a number field K form a countable subset of a torus of dimension r1 +r2 +1 where r1 and r2 are the numbers of real and pairs of complex embeddings.
Function atan2() takes two arguments: x-coordinate and y-coordinate, and calculate the angle in radians for the quadrant. Two other functions atan2f() and atan2l() are also present in C to specifically work with float and long double respectively.
Their versatility also extends to chemical structure in that, although the urethanes are generally considered to be thermosets, there are grades of urethane elastomers that are thermoplastic in nature and are supplied in pellet form for molding, calendering and extrusion.
