Which of the following best describes the difference in bonding between two hydrogen atoms and two carbon atoms?
valentinak56 [21]

Answer :

2. Hydrogen forms bonds through the overlap of 1s atomic orbitals and the sharing of electrons between atoms. Carbon forms bonds through the overlapping of sp hybrid atomic orbitals and the sharing of electrons between carbon atoms.

Explanation:

The H-H bond is formed by the overlap of two 1s orbitals and the sharing of electrons between the two atoms.

A carbon atom must use the overlap of hybridized atomic orbitals and the sharing of electrons to bond with another carbon atoms.

1. is <em>wrong</em> because H can use only its <em>1s orbital</em> for bonding.

3. is <em>wrong</em> because C must <em>share electrons</em> to form a carbon-carbon bond.

4. is <em>wrong</em> because <em>C does NOT use overlapping of 2s orbitals</em> for bonding. It uses the overlap of hybridized orbitals.

5. is <em>wrong</em> because H must <em>share electrons</em> to form an H-H bond.

The shape of a molecule is trigonal planar. How many electron domains around the central atom does this molecule most likely hav
soldi70 [24.7K]
I would think that the answer would be three

Because of the prefix tri- in "tigonal"

Tri- means 3, as in tricycle or triangle

So, it would make sense for the answer to be 3
