Q 9.3: how many triplets would you expect to observe in the 1h nmr spectra for o-chlorotoluene
agasfer [191]
Hello!

You would expect to observe 2 triplets in the ¹H NMR spectra for o-chlorotoluene. 

Multiplicity observed in ¹H NMR spectra when the atom couples with a neighbor ¹H atom. The multiplicity is equal to N+1 where N is the number of neighbor atoms. 

To observe a triplet, you'll need a molecule with 2 neighbor atoms. In o-chlorotoluene (shown in the figure), only protons C and D have 2 neighbor atoms (B and D; A and C, respectively), so you'll expect to see a 2 triplets. 

Have a nice day!

How much heat is needed to raise the temperature of 7g of water by 19oC?
AlekseyPX
Data:

m = 7 g

ΔT = 19 °C

Cs of water = 1 cal / g °C

Formula Q = m * Cs * ΔT

Solution:

Q = (7 g) * (1 cal / g °C) * ( 19°C) = 133 cal

If a buffer has an initial pH of 6.34 and the acid has a Ka of 3.46 × 10-4, what is the ratio of conjugate base to weak acid in
Sloan [31]

Answer: The ratio of conjugate base to weak acid in the buffer system is 758 : 1

Explanation:

The dissociation constant for  acid = K_a=3.46\times 10^{-4}

pH = 6.34

First we have to calculate the value of pK_a.

The expression used for the calculation of pK_a is,

pK_a=-\log (K_a)

Now put the value of K_a in this expression, we get:

pK_a=-\log (3.46\times 10^{-4})

pK_a=3.46

Now we have to calculate the ratio of conjugate base to weak acid in the buffer system

Using Henderson Hesselbach equation :

pH=pK_a+\log \frac{[\text {conjugate base}]}{[Acid]}

Now put all the given values in this expression, we get:

6.34=3.46+\log \frac{[\text {conjugate base}]}{[Acid]}

\frac{[\text {conjugate base}]}{[Acid]}=758

Therefore, the ratio of conjugate base to weak acid in the buffer system is 758: 1

2. All metals are good conductors because their electrons can
dsp73

Answer: An insulator would be made out of material unable to conduct electricity due to lack of fluid movement for electrons, such as rubber. Rubber properties not only prevents them from freely moving, but also helps electrons stay tightly bound to each other.

Hope this helps ^_^
