Draw structures for all constitutional isomers with the molecular

What would happen if a hot piece of iron were placed in a bucket of water at room temperature? How do you know?

BaLLatris [955]

Answer: Eventually, the metal will cool down and warm up. Overtime the metal and the water will come to the same temperature. This happens because the hot metal is giving energy to the water.

Explanation:This process is called thermal equilibrium. It's the same thing as when you put a spoon in hot tea the spoon gets hot and the tea cools down. Hope this helps!!

These should be as similar as possible to the real thing

Elza [17]

The correct term that refers to the description that these should be as similar as possible to the real thing is called models. A model serves as a representation of the actual thing which can be used to explain a phenomenon that cannot be experienced directly. It is just a way to help us better understand what the idea, the object or the event is and should not be taken as the real thing.

Ethene (c2h4) can be halogenated by this reaction: c2h4( g) + x2( g) ∆ c2h4x2( g) where x2 can be cl2 (green), br2 (brown), or i

scZoUnD [109]

Answer :The correct order for equilibrium constant = K₁ > K₂ >K₃

Ethene is an alkene and X2 is elemental halogen . The reaction between alkene and halogen is known as Halogenation reaction . This reaction involves electrophilic addition mechanism . In this reaction elemental halogen (X₂ ) produces a elctrophile , X⁺ . This electrophile is attracted by the double bond in alkene and attached to it .

Due to addition of electrophile , it produces carbocation intermediate .On this positive carbon , nucleophile attacks , hence , a resultant 1,2-di halide alkane is produced .( in image )

The reaction between ethene ( C₂H₄) and halogen ( X₂) produces 1,2 - dihalide ethane (C₂H₄X₂) . The image shows reaction between chlorine ,Cl₂ , a halogen (X₂) .

The expression for equilibrium constant of reaction between ethene and halogen is given as:

$K = \frac{product}{reactant }$

Product = C₂H₄X₂ Reactants = C₂H₄ and X₂

$K = \frac{[C_2H_4X_2]}{[C_2H_4] [X_2]}$

On applying this concept in figures :

Given : Green = Cl₂ Brown = Br₂ Purple = I₂ Grey = Ethene

Grey + Green = 1,2- dihalide ethane

a) Number of Cl₂(green ) = 2

number of ethane ( grey ) = 2

Number of 1,2-dichloride alkane( grey + green ) = 8

Plugging these number in equilibrium constant expression :

$K_1 = \frac{8}{2 * 2 } = \frac{8}{4} = 2$

Hence K₁ for ethene + chlorine = 2

b) Number of Br₂(brown ) = 4

number of ethane ( grey ) = 4

Number of 1,2-dibromide alkane( grey + brown ) = 6

On plugging these values in K expression as :

$K_2= \frac{6 }{4 * 4 } = \frac{6}{16} = 0.375$

Hence K₂ for ethen + Bromine = 0.375

c) Number of I₂(purple ) = 7

number of ethane ( grey ) = 7

Number of 1,2-diiodide alkane( grey + purple ) = 3

On plugging values in K expression as:

$K_3 = \frac{3}{7 * 7 } = \frac{3}{49} = 0.0612$

Hence K₃ for ethene + Iodine = 0.0612

So , the order of equilibrium constant (K) from largest to smallest :

K₃ = 0.0612 K₂ = 0.375 K₁= 2

K₁ > K₂ >K₃
