Which of these chlorocarbons has the highest boiling point? ch2cl2 ccl4 chcl3 ch3cl?

2 answers:

8 0

I think the compound that has the highest boiling point is CCl4
This is because it has four Carbon-Chloride bonds , while the others have three, two and one and Carbon-hydrogen bonds.
Carbon-Chloride bonds are stronger compared to the Carbon-hydrogen bond, therefore in this case the compound with more C-Cl will have more boiling point.

Answer: CCl4

Explanation: Out of CH2Cl2, CCl4, CHCl3 and CH3Cl, CCl4 has highest boiling point.

Boiling point of the liquid is defined as the temperature at which the vapor pressure of the liquid becomes equal to the external pressure of the atmosphere.

It depends on the strength between the molecules and the large surface area.

As larger surface area will lead to the large experience towards the vander wall forces of attraction. Thus CCl4 has larger surface area than the other chlorocarbons . It will experience more vander wall forces of attraction than the other.

How many valance electrons does group #11 have?

galina1969 [7]

It would have 11 valance electrons.

Example/Explanation:

Say we are talking about groups 10. Group 10 would have 10 valance electrons because of the atom's electronic arrangement in the periodic table.

For the reaction, X + Y → A + B, ΔGo is –1324 kJ. Which one of the following statements is NOT valid concerning the reaction?

natima [27]

Answer:

c. The reaction will proceed rapidly from left to right.

Explanation:

The variation of the free Gibbs energy doesn't tell anything about the speed of reaction.

On the other hand, when ΔGo is negative: the reaction is spontaneous, thermodynamically favourable, and the products are more stable than the reactants

Acetylene, C2H2, can be converted to ethane, C2H6, by a process known as hydrogenation. The reaction is C2H2(g)+2H2(g)?C2H6(g)

Alecsey [184]

Answer:

Keq =1.50108

Explanation:

The given reactionis

C₂H₂(g) +2H₂(g) -------------> C₂H₂(g)

ΔG0 f=ΔG0f n (products) - ΔG0f n (reactants )

= -32.89 kJ/mol - (209.2 kJ/mol+2*0.0 kJ/mol)

= - 242.09kJ/mol

ΔG= -RTlnKeq

ln Keq = -ΔG/RT

=-(- 242.09kJ/mol ) / 2 k cal /mol*298 K

=0.406

Keq =e0.406

Keq =1.50108

8. What is the heat of reaction when hydrogen and oxygen combine to form water?

valina [46]

Answer:

The heat of reaction when hydrogen and oxygen combine to form water is :

Explanation:

Enthalpy Change = The enthalpy change for the formation of 1 mole of the substance from their standard state is called the enthalpy of formation.

This is intensive quantity as it is fixed for 1 mole .

Intensive properties = Those properties which are independent on the amount of the substance are intensive properties.

The value of these quantities does not get halve if you divide the substance into two equal parts. example , density, refractive index.

However , the enthalpy of reaction is extensive. Because on increasing the amount the value of the enthalpy also get doubles

Hence for this reaction :

$2H_{2}(g)+O_{2}\rightarrow 2H_{2}(l)$

Its value is -285.8 kJ for 1 mole

And here two moles are present . so the value of molar enthalpy is:

-285.8 x 2 = -571.6 kJ
