root is the user name or account that by default has access to all commands and files on a Linux or other Unix-like operating system. It is also referred to as the root account, root user and the superuser.
Non Polar The bonds themselves between phosphorus and chlorine are polar because chlorine is more electronegative than phosphorus.However the molecule is non polar because th â¦ e five regions of electron density are the same.1 person found this useful.he â¦ bond  angles are less than tetrahedral, 93 o compared to  tetrahedral angle of 109.5 o, there are four electron  pairs, three bonds and the lone pair give the molecule a distorted  tetrahedral electron arangement, (VSEPR thoery).
The bonds are arranged symmetrically around the central C atom and because the bond dipoles cancel, the molecule is non-polar. QUESTION (2011:1) (c) For each of the following molecules: (i) Circle the phrase that describes whether the molecule contains a polar bond or a non-polar bond.Cl 4 nonâpolar molecule The molecule is tetrahedral, due to 4 electron repulsions around the central C atom. The CâCl bond is polar, due to the difference in electronegativity of C and Cl. As these polar bonds are symmetrical about the C atom in CCl 4, the effect of them is cancelled, so the molecule is non-polar.
