What is the IUPAC name for this molecule above?
with explanation step

3,4–diethylheptane

Explanation:

To name the compound given in the question above, the following must be obtained:

1. Determine the functional group of the compound.

2. Determine the longest continuous carbon chain. This gives the parent name of the compound.

3. Identify the substituent groups attached to the compound.

4. Give the substituent groups the lowest possible count by naming them alphabetically.

5. Combine the above to obtain the name of the compound.

Now, we shall name the compound given in the question above as follow:

1. The compound belongs to the alkane family since it has only single bonds.

2. The longest continuous carbon chain is 7 i.e the parent name of the compound is heptane.

3. The substituent group attached to the compound is ethyl (–CH2CH3). There are two ethyl groups attached to the compound.

4. The two ethyl group is at carbon 3 and 4 (i.e number from the right to the upper branch chain).

5. The name of the compound is:

3,4–diethylheptane.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
