What is the IUPAC name of the following compound?
1 answer:
Answer:
2,2,3-trimethylbutane
Step-by-step explanation:
Here are the rules for naming alkanes.
1. Find the longest continuous chain of carbon atoms.
There is a <em>four-carbon chain</em> (blue).
2. Name the main chain.
The chain has four C atoms, so its base name is <em>butane</em>.
3. Identify and name all the substituents.
There are three CH₃ groups (<em>methyl</em><em>,</em> blue bonds).
4. Number the main chain from the end that gives the lowest possible locants to the substituents.
From the left-hand end, the locants are 2,2,3. From the right-hand end, they are 2,3,3. The first point of difference is the second locant. 2 < 3, so we <em>number from the left</em>.
5. Put the names of the substituents with their locants in alphabetical order in front of the base name with no spaces.
Use numbers to connect numbers and hyphens to connect numbers and letters.
The IUPAC name is 2,2,3-trimethylbutane.

A phospholipid structure is shown in the picture attached. It has three parts: the hydrophobic tail, the hydrophilic head and the phosphate group in the center. Thus, the function of the phosphate group is to link the hydrophobic and hydrophilic parts of a phospholipid. Specifically, the phosphate group is part of the hydrophilic head. So, it is used to connect the phospholipids to polar compounds.
