Answer:
pH scale
Explanation:
pH scale -
In the field of chemistry , the accurate and exact value of acidity or basicity in a particular solution is calculated with the help of a pH scale .
The scale has reading ranging from 1 to 14 ,
where ,
- If the pH value less than 7 indicates the solution to be acidic in nature ,
- If the pH value is exactly equal to 7 , the solution is neutral in nature ,
and ,
- If the pH value more than 7 indicates the solution to be basic in nature ,
Hence , from the given statement of the question ,
The correct answer is pH scale .
According to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in alphabetical without taking prefixes into name.
A hydrocarbon would be an organic molecule in organic chemistry that is made completely of hydrogen as well as carbon. A good example of group 14 hydrides includes hydrocarbons. In general, hydrocarbons lack color and are hydrophobic. Typically, their faint smells are compared to that of gasoline and lighter fluid.
- The longest unbroken carbon chain should be found and named.
- Name the groups that make up this chain but instead identify them.
- Beginning at the end of the chain closest to a substituent group, fraction the chain sequentially.
- Give each substituent group a corresponding number but also name to indicate its placement.
Therefore, according to the iupac convention, alkyl substituents on a hydrocarbon chain should be listed in alphabetical without taking prefixes into name.
