Chapter 9: Q9.83CP (page 376)

What would be the formula for the simplest compound formed from (a) phosphorus and chlorine, (b) carbon and fluorine, and (c) iodine and chlorine?

Short Answer

Expert verified

The simplest compound and their respective Lewisstructures are given below

(a)One of the simplest compounds ofphosphorus and chlorineisPCl3

(b)One of the simplest compounds ofcarbon and fluorineisCH4

(c) One of the simplest compounds of iodine and chlorine isICl

Step by step solution

01

Phosphorous trichloride

Phosphorous has five valence electrons. It needs three electrons to complete its octet. It shares three of its electrons with three chlorine atoms which require one electron to complete the octet

02

Carbon Tetrafluoride

Carbon has 4 valence electrons. It needs four electrons to complete its octet. It shares four of its electrons with four fluorine atoms which require one electron to complete the octet

03

Iodine Chloride

Seven valence electrons constitute iodine. It needs 1 electron to complete its octet. It shares one of its electrons with one chlorine atom which requires one electron to complete the octet.

The average C-H bond energy in CH4 is 415kJ/mol. Use table 9.2(p. 353) and the following to calculate the average C-H bond energy in ethane(C2H6;C-C bond), in ethene (C2H4;C=C bond), and ethyne (C2H2;C≡C):

C2H6(g)+H2(g)→2CH4(g)                           ΔHo=-65.07kJ/molC2H4(g)+2H2(g)→2CH4(g)                         ΔHo=-202kJ/molC2H2(g)+3H2(g)→2CH4(g)                         ΔHo=-376.74kJ/mol

Dimethyl ether (CH3OCH3 ) and ethanol (CH3CH2OH ) are constitutional isomers.

a) CalculateΔHorx for the formation of each compound as a gas from methane and oxygen; water vapor forms.

b) state which reaction is more exothermic.

c) calculateΔHorx for the conversion of ethanol to dimethyl ether

Lattice energies can also be calculated for covalent solids using a Born-Haber cycle, and the network solid silicon dioxide has one of the highest ΔHoLatticevalues. Silicon oxide is found in pure crystalline form as transparent rock quartz. Much harder than glass, this material was one prized for making lenses for optical devices and expensive spectacles. Use appendix B and the following data to calculateΔHoLattice of SiO2 :

Si(s)→Si(g)                  ΔHo=454kJSi(g)→Si4+(g)+4e-       ΔHo=9949kJO2(g)→2O(g)                ΔHo=498kJO(g)+2e-→O2-(g)     ​​​   ΔHo=737kJ

Which of the bonds in Problem 9.84 is the most polar?

Rank the members of each set of compounds in order of increasing the ionic character of their bonds. Use polar arrows to indicate the bond polarity of each:

(a) PCI3 , PBr3, PI3

(b) BF3 , NF3 , CF4

(c) SeF4 , TeF4, BrF3
