Answer to Question #108579 in Chemistry for c

Question

the molecule of difluoromethane(CH2F2) which is used as refigerant called R-32:Based on the structure,how many electron domains surround the C atom in this molecule?

Answer 1

The CH₂F₂ molecule structure is shown below.

The central atom, carbon, has four valence electrons. Hydrogen atoms contribute one electron each, making 2 electron pairs shared with carbon.

Fluorine atoms have seven valence atoms each, one short of a filled shell. To fill it, they share one electron each with carbon, making 2 shared electron pairs.

A total of four bonding electron pairs surround carbon atom in CH₂F₂. The notation AX₄ corresponds to this molecule: it has a tetrahedral molecular shape and tetrahedral electron domain geometry.

Answer: 4 electron domains surround the C atom in the CH₂F₂ molecule.
