This laissez-faire form of racism is not governmentally sanctioned like the overt Jim Crow laws of the 1950s, and it is not always obvious. Covert racism comes in many forms including unnecessary politeness to a racial group, or the use of political correctness.
A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms â CH 3. The group is often abbreviated Me.Such hydrocarbon groups occur in many organic compounds.hile the methyl group is usually part of a larger molecule, it can be found on its own in either of three forms: anion, cation or radical.
CH4, methane, is a gas, and the bonds are 97% covalent. SO4^2- is the sulfate polyatomic ion. The bonds in sulfate ion are 83% covalent. In Na3PO4 the bonds in the PO4^3- polyatomic ion are 68% covalent and the bonds between O and Na are 80% ionic. Therefore, Na3PO4 will have high ionic character.
