X-rays are found in the given region.
Answer: Option B
<u>Explanation:</u>
The wavelengths of different waves are studied carefully, and their range is determined according to the frequency they exhibited. And based upon the studies, the electromagnetic waves are classified into eight different categories such as gamma, X-, UV, visible, near IR, middle IR, far IR, micro and radio waves.
And each category has different wavelengths and the given radiation falls under X-rays. The wavelength range of X-rays varies from 1 nm to 1 pm. Here, “nm” stands for nano meter and “pm” stands for “pico meter”.
Answer:
i think it's variable pressure
if not soo advance sorry :)
Answer:
Trinitrobenzoic acid > para nitro benzoic acid>benzoic acid
Nulceophilic acyl Substitution increases by electron withdrawing group (NO2) more the no of withdrawing groups more the reactivity
Since withdrawing group increases positive charge hence nucleophilie readily reacts.
Acidity of Carboxylic acid is explained by inductive effect
Withdrawing group (halogen) increases the acidity and acidity decreases with increasing the distance between halogen and COOH group
And lower the acidity higher the pka and Vice-Versa.
Hence 2-Chlorobutanoic acid has lower pka and more acidic than 3-chloro and 4-chlorobutanoic acids
