Determine the molecular geometry about each interior atom and draw each molecule. (Skeletal structure is indicated in parentheses.) a. N2 b. N2H2 (HNNH) c. N2H4 (H2NNH2)<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n
. N\u2082 (Nitrogen Gas)<\/strong><\/h3>\n\n\n\n
Molecular Geometry:<\/strong><\/p>\n\n\n\n
\n
The molecule consists of two nitrogen atoms connected by a triple bond, with no lone pairs on either atom.<\/li>\n\n\n\n
The electron geometry and molecular geometry for N\u2082 are both linear<\/strong>.<\/li>\n<\/ul>\n\n\n\n
Explanation:<\/strong><\/p>\n\n\n\n
\n
In N\u2082, each nitrogen atom has a lone pair and forms a triple bond with the other nitrogen. This results in a linear molecular shape, with bond angles of 180\u00b0<\/strong>. Since there are no lone pairs affecting the geometry, the bond angle remains straight.<\/li>\n\n\n\n
The structure of N\u2082 can be represented as: N \u2261 N<\/strong> (triple bond between the nitrogen atoms).<\/li>\n<\/ul>\n\n\n\n\n\n\n\n
b. N\u2082H\u2082 (Diazene or Hydrazine)<\/strong><\/h3>\n\n\n\n
Molecular Geometry:<\/strong><\/p>\n\n\n\n
\n
In N\u2082H\u2082, there are two nitrogen atoms, each bonded to one hydrogen atom, with a single bond between them.<\/li>\n\n\n\n
The molecular geometry about each nitrogen atom is trigonal planar<\/strong> for the central nitrogen atoms.<\/li>\n<\/ul>\n\n\n\n
Explanation:<\/strong><\/p>\n\n\n\n
\n
The two nitrogen atoms in N\u2082H\u2082 are connected by a single bond. Each nitrogen is also bonded to a hydrogen atom. The lone pairs on the nitrogen atoms influence the geometry.<\/li>\n\n\n\n
The trigonal planar<\/strong> arrangement arises because there is one bond between the two nitrogen atoms and each nitrogen has two other groups around it (one hydrogen and one single bond to another nitrogen).<\/li>\n\n\n\n
The bond angles are approximately 120\u00b0<\/strong>.<\/li>\n\n\n\n
The skeletal structure for N\u2082H\u2082 is: H-N=N-H<\/strong><\/li>\n<\/ul>\n\n\n\n\n\n\n\n
c. N\u2082H\u2084 (Hydrazine)<\/strong><\/h3>\n\n\n\n
Molecular Geometry:<\/strong><\/p>\n\n\n\n
\n
N\u2082H\u2084 consists of two nitrogen atoms each bonded to two hydrogen atoms, with a single bond between the nitrogen atoms.<\/li>\n\n\n\n
The molecular geometry around each nitrogen is tetrahedral<\/strong>, and the bond angles are approximately 109.5\u00b0<\/strong>.<\/li>\n<\/ul>\n\n\n\n
Explanation:<\/strong><\/p>\n\n\n\n
\n
Each nitrogen atom in N\u2082H\u2084 is bonded to two hydrogen atoms and one nitrogen atom, with a lone pair of electrons on each nitrogen.<\/li>\n\n\n\n
The tetrahedral geometry arises from the lone pairs, as they create repulsion with the bonded atoms, pushing them into a tetrahedral arrangement to minimize electron pair repulsion.<\/li>\n\n\n\n
The bond angles are close to the ideal 109.5\u00b0<\/strong> for a tetrahedral molecule.<\/li>\n\n\n\n
The skeletal structure for N\u2082H\u2084 is: H\u2082N-NH\u2082<\/strong><\/li>\n<\/ul>\n\n\n\n\n\n\n\n
