KCl is an ionized salt which readily dissolved in water and generate potassium and chloride ions. In which potassium posses one unit positive charge and chloride posses one unit negative charge. As water is a polar solvent there are partial positive and negative charge on the hydrogen and hydroxide ion respectively. The high solubility of the potassium chloride (KCl) in water is due to the stabilization of the ions in the polar solvent. The solvation of the ions can be shown as-
Answer:
O2 has a double covalent bond
H2 has a single covalent bond
N2 has a triple covalent bond
Explanation:
Hydrogen atoms form only one covalent bond because they have only one valence electron to pair.
Since two electrons form each bond, there are a total of two pairs, or four electrons, in the bond.
The N2 Lewis structure has a triple bond between two nitrogen atoms. According to the octet rule, nitrogen atoms need to bond three times.
I don’t know but my guess is 80
Answer:
is the major step in forming acid chloride from carboxylic acid and thionyl chloride
Explanation:
- In the first step, -OH group in carboxylic acid gives nucleophilic substitution reaction at S center in thionyl chloride and substitutes -Cl atom
- In the second step, deprotonation takes place by chloride ion.
- In the third step, an intramolecular nucleophilic substitution reaction () takes place where bond electrons rearranges to produce , HCl and thionyl chloride.
- This rearrangement is highly favorable due to formation of gaseous species
- Reaction mechanism has been shown below.
