Answer:
C. 2-methylpropane
Explanation:
There are rules guiding the naming of hydrocarbons. Some of the rules are:
1.) The longest continuous chain is the parent chain:
The longest chain here is made up of 3-carbon atoms which is a propane compound
2.)The carbon atoms are numbered in the parent chain to indicate where branching or substitution takes place.
Here, it is in the second carbon atom in propane.
The branched group is methyl- which is a methane molecule that has lost a hydrogen atom.
This makes ths name of the compound to be:
2-methylpropane
The charge of proton and electron is equal in magnitude that is . The distance between electron and proton is or .
Force exerted on electron by proton is calculated as follows:
Here, k is Coulomb's constant, is charge on proton, charge on electron and r is distance between them.
Putting the values,
Now, according to second law of Newton,
Here, is mass of electron and a is acceleration.
Also,
Rearranging,
Thus, the acceleration of an electron in this atom is .
