What term describes a carbon atom that has four different groups bonded to it?
oee [108]
A carbon which is attached to four different atoms or group of atoms with different environment is called as Chiral Carbon or Asymmetric Carbon.

Non-<span>superimposable:
</span>                                     The mirror image (molecule) of chiral carbon cotaining compounds are Non.Superimposable on each other. They are called enantiomers of each other.

Polarized Light and Chiral Carbon:
                                                       When a polarized light is allowed to fall on either enantiomer of chiral compound, it is rotated other clockwise or anti-clockwise.

Examples:
                Below are three axamples of compounds containing chiral carbon.

Balance the following H2 SO4 + NaOH ==== NaSO + H2O​
katrin [286]

Answer:

H2SO4 + 2NaOH --->   Na2SO4 + 2H2O

Explanation:

H2SO4 + NaOH --->   Na2SO4 + H2O

                Na1    --->     2Na

H2SO4 + 2NaOH --->   Na2SO4 + H2O

2H   +   2H =  4H       ---->                 2H

H2SO4 + 2NaOH --->   Na2SO4 + 2H2O

     4O  + 2O         ----->          4O   +     2O
