See attached picture.
Explanation:
Hello.
In this case, since butane has two common occurring structures, n-butane and isobutane, there is a way in which the tert-butyl radical can be formed upon the removal of a hydrogen from the isobutane form of butane as shown on the attached picture, wherein you can see that the radical is named by "tert" since the central carbon is bonded to three carbon atoms, that is why we classify it as tertiary. Moreover, it is a radical due to the presence of the bolded dot next to the tertiary carbon suggesting that it is very likely to bond with an other atom.
Best regards.
Answer: (a) BE = 1.112 MeV
(b) BE = 7.074 MeV
(c) BE = 7.767 MeV
(d) BE = 8.112 MeV
Explanation: Binding energy per nucleon is the average energy necessary to remove a proton or a neutron from the nucleus of an atom. It is mathematically defined as:
Where
Δm is a difference in mass known as <u><em>mass</em></u><em> </em><u><em>defect</em></u>
A is atomic mass of an atom.
Mass Defect is determined by:
where:
Z is atomic number
is mass of proton
is mass of neutron
is mass of the nucleus
Mass of proton is 1.007825u.
Mass of neutron is 1.008665u.
The unit u is equal to 931.5MeV/c².
(a) 2H(deuterion): Given: Z = 1; A = 2; = 2.014102u
BE = 1.112MeV
(b) 4He (Helium): Given: Z = 2; A = 4; = 4.002603
BE = 7.074MeV
(c) 18O (Oxygen): Given: Z = 8; A = 18; = 17.999160
BE = 7.767MeV
(d) 23Na (Sodium): Given: Z = 11; A = 23; = 22.989767
BE = 8.112MeV
