Answer:
B. Aromatic
Explanation:
Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.
For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.
Answer:
2.2 × 10⁻⁴ m
Explanation:
Step 1: Given and required data
- Energy of the wave (E): 9.2 × 10⁻²² J
- Planck's constant (h): 6.63 × 10⁻³⁴ J.s
- Speed of light (c): 3.00 × 10⁸ m/s
Step 2: Calculate the wavelength (λ) of the wave
We will use the following expression.
E = h × c/λ
λ = h × c/E
λ = 6.63 × 10⁻³⁴ J.s × 3.00 × 10⁸ m/s/9.2 × 10⁻²² J
λ = 2.2 × 10⁻⁴ m
I think they are all incorrect honestly most of them are fake.
