Explanation:
i don't understand sorry :)
The two atoms shown in the equation are CALCIUM and oxygen.
<span>You start off with a neutral calcium atom with a shell of two electrons, a shell of 8 around that, a shell of 8 around that, and a shell containing 2...with no charge. </span>
<span>20 protons + 20 electrons. </span>
<span>You also have an oxygen atom with a shell of 2, and a shell of 6...with no charge. </span>
<span>8 protons + 8 electrons. </span>
<span>Each ionizes to form a calcium ion with 2 electrons removed (from the outer shell), leaving a +2 charge (20 protons, 18 electrons)... </span>
<span>and an oxygen ion with 2 electrons added (to the outer shell), leaving a -2 charge (8 protons, 10 electrons). </span>
<span>Their electrostatic attraction causes them to come together to form an ionic compound of CaO in a crystal lattice.</span>
solution:
That is a one benzene ring.
The really messy multiplet at 7.27ppm pretty much can be interpreted as a monosubstituted ring.
After the ring is accounted for, all that's left is C₂H₃. There's one more double bond equivalent, and only two carbons left, so the only possibility is an alkene.
the alkene protons are the signals at 6.7ppm, 5.6ppm, and 5.2ppm. A benzene ring attached to an alkene will shift the proton geminal to it up about 1.3ppm from the normal 5.25ppm, the cis proton up about 0.36ppm, and have not much effect on the proton trans to it.
same family or group called Alkali metals
