Problem 6Q

Describe the geometry about a carbon atom that forms:

(a) four single bonds

(b) two single bonds and one double bond

(c) one single bond and one triple bond

Step-by-Step Solution:
Step 1 of 3

Answer :

(a) four single bonds

When carbon forms four bonds with atoms, its shape is called a tetrahedron. ... A valence electron is an electron that occupies the outer shell of an atom. Each bond in a molecule equals two valence electrons.

(b) two single bonds and one double bond

A double bond in chemistry is a chemical bond between two chemical elements involving four bonding electrons instead of the usual two. The most common double bond, that is between two carbon atoms, can be found in alkenes. Many types of double bonds exist between two different elements. For example, in a carbonyl group with a carbon atom and an oxygen atom. Other common double bonds are found in azo compounds (N=N), imines (C=N) and sulfoxides (S=O). In skeletal formula the double bond is drawn as two parallel lines (=) between the two connected atoms;

(c) one single bond and one triple bond

Alkynes, containing a carbon-carbon triple bond, have the linear or straight geometry as a primary feature.

A portion of the molecule is in a straight line and really only 1-dimensional.

Alkynes - 2 atoms and 1 triple bond = linear

Chime in new window

Ethyne or acetylene, HC=CH, is the simplest alkyne example.

Since a triple bond is present and each carbon is attached to 2 atoms (1 H and 1 C), the geometry is linear. This linear feature extends through a total of four atoms.
