Chapter 13: Q93E (page 554)

Question: Write the name of each of the following molecularstructures

Short Answer

Expert verified

Answer:

  1. V-shape or bent
  2. See-saw
  3. Trigonal pyramidal
  4. Trigonal bipyramidal
  5. Tetragedral

Step by step solution

01

Explanation of part (a)

This is a V-shape or bentstructure. This shape is represented by a compound which shows tetrahedral geometry and having two pairs of electrons on the central atom for example H2O

02

Explanation of part (b)

This is a see-sawshape structure. This shape is represented by a compound which shows trigonal bipyramidal geometry and having one pair of electrons on the central atomfor example SF4

03

Explanation of part (c)

This is a trigonal pyramidalstructure. This shape is represented by a compound which shows tetrahedral geometry and having one pair of electrons on the central atom for exampleNH3.

04

Explanation of part (d)

This is a trigonal bipyramidalstructure. In this structure shape and geometry is the same because there is no lone pair on the central atom for example PCl5

05

Explanation of part (e)

This is a tetrahedral structure. In this structure shape and geometry is the same because there is no lone pair on the central atom for example CH4

Question: Considering your answers to Exercise 64, what conclusions can you draw concerning the structures of species containing the same number of atoms and the same the number of valence electrons?

Arrange the following molecules from most to least polar, and explain your order: CH4, CF2Cl2, CF2H2, CCl4, and CCl2H2.

Question: Nitrous oxide (N2O) has these possible Louis structure:

Given the following bond lengths,

N-N167pmN=O115pmN=N120pmN-O147pmN≡N110pm

Rationalize the observations that the N-N bond length in N2O isand that the N-O bond length is 119 Pm. Assign formal charges to the resonance structures on the basis of formal charges? Is this consistent with observation?

Question: A common trait of simple organic compounds is to have Lewis structures where all atoms have a formal charge of zero. Consider the following incomplete Lewis structure for an organic compound called methyl cyanoacrylate, the main ingredient in Super Glue.

Draw a complete Lewis structure for methyl cyanoacrylate in which all atoms have a formal charge of zero.
