Answer:
As we are not provided with ¹H-NMR spectrum therefore we can not conclude a single result for the minor chlorination of propane with Molecular formula C₃H₆Cl₂.
Hence, we will draw all the possible isomers with molecular formula C₃H₆Cl₂ and predict the ¹H-NMR spectrum for each of them separately.
Below is the structures of possible minor products and the NMR spectrum respectively.
Possible Product A:
If the minor product formed is 2,2-Dichloropropane then it will give only one singlet peak in NMR spectrum.
Possible Product B:
If the minor product is 1,1-Dichloropropane then it will exhibit two triplets and one multiplet as shown in figure.
Possible Product C:
If the minor product is 1,2-Dichloropropane then it will give four peaks in NMR. The extra peak is formed due to two enantiomers about the chiral carbon.
Possible Product D:
If the minor product is 1,3-Dichloropropane then it will exhibit one triplet and one quintet signal as shown in figure.
Answer: D. Series circuits are simpler than parallel circuits.
Explanation:
In series circuit, all the components are connected in single path of current flow.
If one part of the circuit breaks, complete circuit would break and all the other parts also would not operate.
The voltage is not same everywhere. It is different across each component.
In series circuit, net resistance is more as resistance of all the components connected in series are added up.
So, the only advantage of a series circuit is that is simpler than the parallel circuits. Thus, the correct option is D.
A lower pH means that there are extra hydrogen ions in the liquid, whereas a higher pH indicates fewer hydrogen ions in the liquid. In simple terms, pH is a scale from 1 to 14 that measures the acidity or alkalinity of a liquid.
The hydrated ion undergoes hydrolysis in solution producing `H3O+ . This occurs because the Be-O bond is very strong and so in the hydrated ion and it weakens the 0-H bond. Hence, there is a strong tendency to lose protons. For this particular reason, the aqueous solution of `BeCl_2` is acidic in nature.
<h3>Will baking soda decrease pH?</h3>
Baking soda, also regarded as sodium bicarbonate is naturally alkaline, with a pH of 8 When you add baking soda to your pool water, you will increase both the pH and the alkalinity, improving balance and clarity. Many industrial pool merchandise for elevating alkalinity utilize baking soda as their most important active ingredient.
