Answer:
2-hexanone
Explanation:
First, we'll begin by:
1. Locating the longest continuous chain i.e haxane
2. Determine the functional group in the compound. The functional group in ketone (C=O). This changes the name from hexane to hexanone i.e replacing the -e in at the end in hexane with -one to make it hexanone.
3. Give the functional group the lowest low count. In doing this, we'll start counting from the left. The functional group is at carbon 2.
Note: no substitute group is attached.
Now, in naming the compound, we must indicate the position of functional group as illustrated below:
The name of the compound is:
2-hexanone
The heat energy from the fire is transferred to the pot by
- <em>radiation</em> — the hot coals radiate heat to the pot.
- <em>convection</em> — the hot gases from the fire travel upward until they reach the pot
The pot absorbs the heat energy and <em>conducts</em> the heat to the water inside.
The hot water <em>conducts</em> heat to the peas in three steps:
- warming the frozen ice and peas to 0 °C.
- thawing the ice and peas at 0 °C.
- heating the peas to 100 °C and cooking them at that temperature.
<em>Note</em>: Heat always flows spontaneously from a hotter to a cooler object.
