STEP 1

1. Dicarbon tetrahydride is a molecule with the chemical formula $\text{C}_2\text{H}_4$ .
2. The central carbon atom refers to one of the carbon atoms in the molecule.
3. The molecule is ethylene, which is a common name for dicarbon tetrahydride.

STEP 2

1. Determine the number of valence electrons around the central carbon atom.
2. Identify the number of electron domains around the central carbon atom.
3. Determine the number of bonding directions around the central carbon atom.
4. Identify the molecular shape around the central carbon atom.

STEP 3

Determine the number of valence electrons around the central carbon atom:
- Each carbon atom has 4 valence electrons. - In ethylene ( $\text{C}_2\text{H}_4$ ), each carbon shares electrons with two hydrogen atoms and one other carbon atom.
Thus, the number of valence electrons around the central carbon atom is $4$ .
Blank 1: $4$

STEP 4

Identify the number of electron domains around the central carbon atom:
- Each carbon atom in ethylene forms three sigma bonds (two with hydrogen atoms and one with the other carbon atom) and one pi bond (with the other carbon atom). - The sigma bonds represent three electron domains.
Thus, the number of electron domains is $3$ .
Blank 2: $3$

STEP 5

Determine the number of bonding directions around the central carbon atom:
- The bonding directions are determined by the number of sigma bonds, which is $3$ .
Blank 3: $3$

STEP 6

Identify the molecular shape around the central carbon atom:
- With three electron domains, the molecular shape is Trigonal Planar.
Blank 4: Trigonal Planar
The completed blanks are:
Blank 1: $4$
Blank 2: $3$
Blank 3: $3$
Blank 4: Trigonal Planar
