AB  - This study presents an easy and quick method for the synthesis of graphene from 
      graphite in a set of solvents, including n-Hexadecane (n-Hexa), dimethylsulfoxide 
      (DMSO), sodium hydroxide (NaOH), 1-octanol (OCTA), perchloric acid (PA), 
      N,N-Dimethylformamide (DMF), ethylene glycol (EG), and ethylene diamine (ED), via 
      microwave (MW) energy. The properties of final products were determined by X-ray 
      diffraction spectroscopy (XRD), Fourier transform infrared spectroscopy (FTIR), 
      ultraviolet-visible (UV-Vis) spectroscopy, and the four-point probe technique. 
      The XRD spectra of most of the MW-assisted graphene products showed peaks at 2theta = 
      26.5 degrees  and 54 degrees . Layer numbers extend from 2 and 25, and the leading comes about 
      were gotten by having two-layered products, named as graphene synthesized in 
      dimethylsulfoxide (G-DMSO), graphene synthesized in ethylene glycol (G-EG), and 
      graphene synthesized in 1-octanol (G-OCTA). G-DMF has the highest electrical 
      conductivity with 22 S/m. The electrical conductivity is higher when the dipole 
      moment of the used solvent is between 2 and 4 Debye (D). The FTIR spectra of most 
      of the MW-assisted graphene products are in line with commercial graphene (CG). 
      The UV-Vis spectra of all MW-assisted graphene products showed a peak at 223 nm 
      referring to characteristic sp2 C=C bonds and 273 nm relating to the n --> pi * 
      transition of C-O bonds.
