H2 is known to exist. For dihydrogen, H2, we can identify the frontier molecular orbitals (FMOs). The highest occupied molecular orbital (or HOMO) is the σ (sigma) 1s MO. The lowest unoccupied MO (LUMO) is the σ* (sigma star) 1s MO which is antibonding.
The CH4 molecule has the lowest molecular weight, so it has the lowest boiling point.
Hope I helped :)
Answer: False
Explanation: There are four carbon atoms , eight hydrogen atoms and two Bromine atoms.
As the carbon forms four covalent bonds, every carbon must have four bonds and thus the formula of the compound is .
IUPAC name of the compound is 1,2 di-bromobutane. As the carbon chain is 4 atoms long the word used is but and all the bonds are single bonds, thus the suffix used is ane.
Unlike nuclear reactions, nuclear reactions are not affected by changes in temperature,
pressure, of the presence of catalysts. Also nuclear reactions of given radioisotope cannot be slowed down, speeded up, or stopped.
