Answer:
Option A.
Explanation:
To know which structure is correct, let us name both compound.
In naming the above organic compound, the following must be observed:
1. Locate the functional group. In this case it alkene since it has carbon to carbon double bond (C=C).
2. Locate the longest continuous carbon chain. In this case the compound is a cyclic compound with 6 carbon i.e cyclohexene.
3. Locate the substituents attached to the compound. In this case, bromine (bromo) and chlorine (chloro) are the substituents attached.
4. Locate the position of the substituents and name alphabetically counting from the double bond. In this case, bromo comes before chloro
5. Combine the above to get the name.
For option A, the name is:
4–bromo–5–chlorocyclohexene.
For option B, the name is:
3–bromo–4–chlorocyclohexene.
We can see that Option A gives the correct structure of the compound.
Answer:
Carbon has a total of four bonded pairs of electrons around it.
Explanation:
Since there are four "lines" around the C (which stands for Carbon), we can conclude that Carbon has a total of four bonded pairs of electrons around it.
Answer:
Pb(NO3)2 + 2NaCl = 2NaNO3 + PbCl2
The unit expressed in 660 nm of light represents the wavelength of light. If you want to determine the frequency, you use the speed of light to relate the two. The formula is:
c = λν
where
λ is the wavelength
ν is the frequency
c is the speed of light = 3×10⁸ m
Apply SI units:
(3×10⁸ m) = (660×10⁻⁹ m)(ν)
Solving for ν,
<em>ν = 4.55×10¹⁴ s⁻¹</em>
