Rank the following from highest to lowest priority according to the Cahn-Ingold-Prelog system: -CH2CH3, -CHCH2, -CCH, -CH3.
mario62 [17]

Answer:

The order will be:

CCH > CHCH₂ > CH₂CH₃> CH₃

Explanation:

According to Cahn-Ingold-Prelog system we rank the groups based on the atomic number of directly attached atom with the chiral carbon.

For example: between C and H, we rank Carbon first.

If the same atoms are attached for different groups then we prioritized based on the second element with highest atomic number.

For example:

Among CH₃ and C₂H₅, the priority will be given to C₂H₅.

If an atom is double or triple bonded to the directly attached atom then each pi bond is considered to be a new atom.

Hence CH=CH₂ means, that there are two carbons attached to CH carbon.

So the order based on above selection rules will be:

CCH > CHCH₂ > CH₂CH₃> CH₃

A property is a characteristic of a substance that can be observed and does not change the identity of the substance. T/F
Murljashka [212]
The correct answer is false. The statement given does not describe a property in general. However, it speaks of a specific type of property which is the physical property.  This property is the one that does not change the identity of a substance. A property can also be a chemical property where the identity of a substance is changed.

ASHA 777 [7]
<span>There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. So, we calculate as follows:

Molarity =  15.9 g BaCl2 ( 1 mol / 208.23 g ) / .375 L = 0.204 mol / L</span>

What can be said about an endothermic reaction with a negative entropy change?
zvonat [6]
The statement is false because endothermic reactions have a positive enthalpy change, because heat is being added to the system because it requires more energy to react
